There is provided a water dissolvable tampon applicator comprising a first polyvinyl alcohol, a second polyvinyl alcohol having a lower percent hydrolysis than said first polyvinyl alcohol, a plasticizer. Preferably, the first polyvinyl alcohol is polyvinyl alcohol 98% hydrolyzed ultra low viscosity, the second polyvinyl alcohol is polyvinyl alcohol 88% hydrolyzed ultra low viscosity, and the third polyvinyl alcohol is polyvinyl alcohol 88% hydrolyzed low viscosity. The applicator also includes a plasticizer and an antioxidant. The applicator further includes a water insoluble coating that holds moisture. The water insoluble coating is preferably a vinylidene chloride copolymer, and can be used on any polyvinyl alcohol tampon applicator. In another preferred embodiment, the applicator is exposed to humidity prior to application of the coating.

Thermoplastic polymer compositions comprise a polyphenylene ether resin, s styrene resin and a hygroscopic salt in an amount sufficient to provide the compositions with antistatic properties. Preferably, the hygroscopic salt comprises lithium chloride and is included in an amount of from about 0.5 to about 5 parts by weight per hundred parts by weight resins.

Antistatic PPE compositions and methods

Ultra-fine polymeric fibers are produced from various polymeric materials by mixing with thermoplastic poly(vinyl alcohol) and extruding the mixture through a die followed by further orientation. The poly(vinyl alcohol) is extracted to yield liberated ultra-fine polymeric fibers. The polymer utilized can include post-consumer polymer waste.

Process for the production of ultra-fine polymeric fibers

A novel product is disclosed for cleaning up oil spills. The product comprises ultra-fine polymeric fibers which are produced from various polymeric materials by mixing with thermoplastic poly(vinyl alcohol) and extruding the mixture through a die followed by further orientation. The poly(vinyl alcohol) is extracted to yield liberated ultra-fine polymeric fibers. The fibers are ultimately processed into said product, such as a mat, which is placed directly on the oil spill to absorb the oil.

Fibrous material for oil spill clean-up

The melt flow behavior of blends of polyphenylene ether resins and alkenyl aromatic resins such as high impact polystyrene can be markedly improved by incorporation therein of effective amounts of styrene-alpha methyl styrene copolymers.

Polyphenylene ether compositions having improved flow

Novel flame retardant agents comprise polyalkylene oxides or a derivative thereof and end-capped with brominated phthalimide groups, and have the general formulae ##STR1## R.sup.1 is alkylene of from about 2 to about 6 carbon atoms; R.sup.1 is alkyl of from about 1 to about 6 carbon atoms; n is from about 4 to about 40; n' is from about 3 to about 15; and n' is from about 1 to about 10. Thermoplastic compositions, for example, polyphenylene ether compositions, rendered flame retardant with the novel compounds have a high resistance to additive vaporization and surface liquid exudation as well as desirable high flow characteristics.

Flame retardant alkenyl aromatic compounds which are vinylbenzyl diaryl phosphine oxides and a method for their preparation are described. They may be polymerized into higher molecular weight flame retardant materials which, in turn, may be admixed with polyphenylene ether resins to form thermoplastic flame resistant molding compositions. The present materials are more resistant to losses in the flame retardancy upon thermal processing, e.g., molding, because the active flame retardant agent, phosphorus, is chemically bound to the polymeric matrix.

Flame resistant alkenyl aromatic compounds and polymers containing

A method for increasing the heat distortion temperature of certain blends of polyphenylene ether resin and styrene polymers is described in which an admixture is formed of a polyphenylene ether resin and a flame retardant copolymer of styrene and up to 50 percent dibromostyrene. The resulting compositions can be formulated to include one or more additional ingredients and are moldable into articles characterized by good flame retardancy and light stability, as well as a higher heat distortion temperature compared with articles formed from corresponding blends using homopolystyrene or styrene-bromostyrene copolymer.

Flame retardant polyphenylene ether-polystyrene blends of increased heat

Aryl phosphates are prepared by a procedure in which a diaryl cabonate is reacted with phosphoric acid or a phosphate derived from the acid, using an added source of hydrogen ions, for instance, methanesulfonic acid, to catalyze the reaction.

Process for preparing aryl phosphates

Flame retardant admixtures of triaryl phosphates and a resin as well as a process for preparation are described. The triaryl phosphate mixture includes at least one phosphate where 1 or 2 of the 3 aryl groups are mesityl and the remaining group or groups are independently selected from among phenyl and xylyl. The triaryl phosphate mixture provides better flame retardancy per unit weight of phosphorous than, for instance, triphenyl phosphate alone or trimesityl phosphate alone.

Flame retardant mixture of triaryl phosphates and resinous compositions

Flame retardant compositions comprising a polyphenylene ether resin, a styrene resin and a cyclic phosphonate have excellent appearance and physical properties after molding. Especially useful is diphenyl pentaerythritol diphosphonate.

Flame retardant composition of polyphenylene ether, styrene resin and

The melt viscosity of thermoplastic compositions of polyphenylene ether resin and rubber modified high impact polystyrene resin is significantly reduced by inclusion of a tetra-alkyl bisphenol polycarbonate resin. The resulting blend can be processed at lower temperatures, and, after molding, exhibits better UV color stability while retaining most important other physical properties. Both the compositions and a method of preparation are described.

Compositions of polyphenylene ether resin and poly(tetra-alkylated

Polyphenylene ether resins and resin compositions in admixture with trineopentylene diphosphite as a thermal oxidative stabilizer are described. These can be used with or without an impact modifier for the polyphenylene ether resin. An additional benefit is that the resins and compositions exhibit a higher heat distortion temperature.
