Described is a method for imparting a substantive fragrance to fabrics being washed or dried in a washing machine or clothes dryer by means of tumbling the fabrics with one or more sachets, each of which contains fragrance-containing particles. The polymer particles comprise an ethylene-vinyl acetate copolymer, a blend of polyethylene and an ethylene/vinyl acetate copolymer, an ester-terminated polyamide, a blend of an ester-terminated polyamide and a polysaccharide and/or a C&#x2013;Calkyl methacrylate polymer. A method for producing fragrance-containing particles is also disclosed.

Method for imparting substantive fragrance and, optionally, anti-static properties to fabrics during washing and/or drying procedure and compositions useful for effecting such processes

A pollutant treating device especially adapted for motor vehicles in which a housing containing a catalyst composition for treating pollutants is positioned within the normal flow pattern of ambient air within the motor vehicle and is preferably removably placed within a support, such as a bracket assembly where the housing can be readily removed and replaced and/or reused.

Disclosed are formed composite material compositions suitable for use in the removal of heavy metals from aqueous systems, a process for preparing said composite materials and a process for the removal of heavy metals using said composite materials. Formed particulate composite material compositions are comprised of (A) at least one ion exchange material; (B) at least one activated carbon; and, optionally, (C) at least one binder material. The method for preparing said composite material compositions comprises first mixing components (A), (B) and, optionally, (C), then forming particles from said mixture. The method for removing heavy metals from aqueous systems containing one or more heavy metals comprises contacting said aqueous system with one or more of the composite materials until the heavy metals are substantially removed from the aqueous system.

Composite material, preparation and use thereof

Disclosed is a method for removing arsenic from aqueous systems containing arsenic which includes contacting said aqueous system with an adsorbent material comprising (i) activated bauxite and (ii) aluminum trihydrate, until the arsenic is substantially removed from said aqueous system. The adsorbent material is prepared by the steps including (i) mixing powders of activated bauxite and aluminum trihydrate in the presence of water to form granules; (ii) drying said granules; and (iii) calcining said dried granules.

Method for removing arsenic from aqueous systems containing competing

Inorganic hydrated metal oxide and metal silicate gels are supported on the surface of particles of porous material by precipitation therein without significant deposit within pores of the support material and without encapsulating the particles of porous material. Especially preferred hydrated oxides and silicate gels are those of titanium. Preferred porous particles are composed of carbon. These novel composite materials are prepared by spraying an aqueous basic material onto the porous particles and then spraying a concentrated aqueous acidic solution of a source of suitable metallic ions so as to rapidly form a gelatinous precipitate on the surface of the porous particles which remain porous.

Composite ion-exchange material, preparation and use thereof

Thermoplastic blends having superior capability and homogeneity comprising a poly(phenylene oxide) resin and a resin of poly(methyl ethenyl benzene) isomers in which the predominant isomer is 1-methyl-4-ethenyl benzene, are disclosed. The poly(phenylene oxide) resin can contain substituted phenylene units and the poly(methyl ethenyl benzene) resin can be a polymer of solely methyl ethenyl benzene isomers, or a random, block or graft copolymer comprising 50 weight percent or more of methyl ethenyl benzene iosmers and up to 50 weight percent of other ethylenically unsaturated monomers.

Thermoplastic composition containing a poly(methyl ethenyl benzene)

Blends of a preformed poly(methyl ethenyl benzene) polymer or copolymer derived from an isomers of methyl ethenyl benzenes in which 1-methyl-4-ethenyl benzene is the predominant isomers, and up to about 10 weight percent of mineral oil are disclosed.

Compositions comprising a poly(methyl ethenyl benzene) resin and mineral

The present invention provides for an economical thermoplastic bag which may be employed to contain foods during storage and, most importantly, may be used to contain such foods during reheating preparatory to serving. The bag structures of the present invention comprise a two layer laminate structure, the inner bag layer, or that surface layer in contact with the foodstuffs, being formed from a thin film of polyester. The outer layer of the bag laminate, or that surface of the bag which comes into direct contact with the cooking or reheating vessel, comprises a polyacrylonitrile homopolymer. The polyacrylonitrile layer, having a melting or sticking temperature on the order of above 210.degree. C. is stable and will not stick to the vessel side walls while foodstuffs are being reheated therein. Obviously the bag containing foodstuffs is intended to be immersed in a fluid such as water during the reheating operation. Accordingly, the present invention provides laminar bags for the storage and containment of foodstuffs which may subsequently be reheated without first removing them from the bag. In a specific embodiment of the present invention, the bag is constructed from a two-ply laminate comprising an inner film layer of polyester and an outer layer of polyacrylonitrile homopolymer film adhered thereto.

Thermoplastic blends having superior capability and homogeneity comprising a poly(phenylene oxide) resin and a resin of poly(methyl ethenyl benzene) isomers in which the predominant isomer is 1-methyl-4-ethenyl benzene, are disclosed. The poly(phenylene oxide) resin can contain substituted phenylene units and the poly(methyl ethenyl benzene) resin can be a polymer of solely methyl ethenyl benzene isomers, or a random, block or graft copolymer comprising 50 weight percent or more of methyl ethenyl benzene isomers and up to 50 weight percent of other ethylenically unsaturated monomers.

Metallized polymeric film material having a high gloss, mirror-like surface is transformed by means of heat treatment to a material having a smooth lustrous surface appearance not unlike that of satin, or alternatively an apparent rough or granular surface texture (i.e. a matte-like finish). The transformation may be accomplished by directly heating the metallized film material or in conjunction with a laminating/thermoforming operation (for instance: the formation of disposable plastic dinnerware) to produce a rigid article having a pleasing appearance.

Optical transformation of metallized polymeric film material

Epoxide compounds are cured rapidly at relatively low temperatures by reaction products of a carboxylic acid anhydride and an organothiostannoic acid anhydride or mixtures containing these two compounds. The cured products exhibit good physical and electrical properties.

Novel curing agents derived from organothiostannoic acids

Alkali metal salts of carboxylic acids containing from 2 to 20 carbon atoms are unique in comparison to salts of other elements, including stannous octoate, in their ability to retain catalytic activity when stored in the presence of rigid polyurethane foam precursors.

Storage-stable precursors for rigid polyurethane foams

The load-bearing characteristics of high resiliency polyurethane foams, as expressed by the loading required to obtain a 65% reduction in thickness, are significantly improved using as the gel catalyst certain diorganotin mercaptides or mercaptoesters.

Flexible cellular polyurethane exhibiting excellent thermal and oxidative stability can be prepared using specified complexes of organotin halides or pseudo halides with amines, phosphines or phosphine oxides as latent polymerization catalysts. These catalysts also eliminate the shrinkage that often characterizes cellular polyurethanes prepared using organotin compounds as the polymerization catalyst.
