The invention relates to an electroconductive composition comprising a polysiloxane matrix, electroconductive particles dispersed therein and an amount of a nucleophilic chemical species capable of impeding an increase in the resistivity of the composition, the nucleophilic chemical species being substantially unreactive with the particles and the matrix, and not causing any substantial impairment of the tear strength and tensile strength properties of said matrix; electroconductive composite comprising the electroconductive composition; and methods for making the electroconductive composition.

Electroconductive composition composite suitable for making same and methods for producing such composition and composite

As an article of manufacture, particulate composites containing, in combination: particles of inorganic material, a component for conferring on the composites the capability of floating in a medium including one or more substance capable of forming a binder matrix, a component for conferring on the composites the capability of adherence to the binder matrix, and a component for conferring on the composites the capability of adherence of the flotation conferring to the inorganic material; their production; and their use in a binder matrix.

Electroconductive composition and methods for producing such composition

As an article of manufacture, a durable composite, which comprises in combination a glass bead, and a multifunctional polymeric substance which has a functionality capable of interacting with a species of interest, and a further functionality interacted with a functionality of said glass bead to adhere the substance to the glass, such that there is a decreased tendency of the agent toward removal from the composite by an aqueous medium; and a method of making same.

Durable composite particle and method of making same

As an article of manufacture, a composite, which comprises in combination an inorganic material substrate, a polymeric agent which is at least partially water-soluble, and a substance binding the polymeric agent to the inorganic material substrate, such that there is a decreased tendency of the agent toward removal from the composite by an aqueous medium; and methods of making and using same.

Durable polymeric deposits on inorganic material substrate

Composite particles suitable as conductive filler for electrically conductive compositions which can be used as gaskets, caulking and plastics, for example. The compositions are useful as EMI shielding and electrostatic charge dissipation materials. Methods of making and using the foregoing are also covered.

Galvanically compatible conductive filler and methods of making same

As an article of manufacture, stable particles containing, in combination, inorganic filler material, benzoyl peroxide and a non-hygroscopic stabilizer for benzoyl peroxide; their production; and the formation of a polymeric matrix with such particulate matter.

Free-flowing catalyst coated beads for curing polyester resin

Described are thermoplastic or thermoset polymer and resin compositions (e.g., nylon, polyvinylchloride, phenolics, etc.) containing a bis-sulfonamide or polyhaloaromatic monosulfonamide in quantity sufficient to plasticize the resins and polymers. The polyhaloaromatic monosulfonamide contains (a) from 7 to 30 carbon atoms, (b) from 2 to 12 chlorine and/or bromine atoms, (c) one nitrogen atom, (d) an aromatic group, bonded to the sulfur atom, in which at least two chlorine or at least two bromine atoms or at least one chlorine atom and at least one bromine atom are directly bonded to the aromatic ring system, and (e) one or two aliphatic, cycloaliphatic, or aromatic organic groups bonded to the nitrogen atom, one such organic group, when an aromatic group, optionally being substituted by one or more bromine and/or chlorine atoms. The bis-sulfonamide contains at least two aromatic rings and from 14 to 30 carbon atoms in the molecule. These sulfonamides are of advantage in that they have relatively low volatilities and good thermal stability at polymer processing temperatures and serve as flame retardants therein. Bis-sulfonamides having an alkylene bridge group between two sulfonamide groups are particularly suitable as plasticizers for engineering resins such as polyimides, polyamide imides, polyether imides, polyether sulfones, polyether ketones, and engineered polyamides.

Polymer compositions

A flame retardant polypropylene based formulation which contains polypropylene and a flame retardant amount of decabromodiphenyl oxide and a polybrominated cycloalkane having an 8 to 12 carbon atom ring and at least 4 ring-attached bromine atoms.

Flame retardant polypropylene based formulations

Described are themoplastic condensation polymers containing a polyhaloaromatic aromatic flame retardant and an aromatic bis-sulfonamide having at least two aromatic rings and from 14 to 30 carbon atoms melt flow improver. These sulfonamides are of advantage in that they have relatively low volatilities at polymer processing temperatures.

Flame retardant nylon compositions

This invention relates to a styrenic polymer-based thermoplastic formulation containing a brominated cycloaliphatic flame retardant and a thermal stabilizer system comprising an organotin stabilizer, a hindered phenolic antioxidant and, optionally, a polyhydroxy aliphatic compound.

Thermally stabilized styrenic polymer-based thermoplastic formulations

Described are polybromoaromatic bis-sulfonamides containing at least two bromoaromatic groups, from 18 to 30 carbon atoms (preferably 18 to 24), and from 6 to 14 bromine atoms substituted on the aromatic rings. Such polybromoaromatic bis-sulfonamides may be represented by the general formula ##STR1## where Ar are the same or different polybromoaromatic groups, R is a divalent aromatic or bromoaromatic group, and R' and R' are independently hydrogen atoms, hydrocarbon groups or halohydrocarbon groups in which the halogen atoms are chlorine or bromine, the total number of bromine atoms substituted on the aromatic rings of the groups designated as Ar and R falling in the range of 6 to 14. These sulfonamides are useful as flame retardants and plasticizers for thermoplastic polymers and have the advantage of relatively low volatilities at polymer processing temperatures.

Polybrominated bis sulfonamides

Described are thermoplastic polymers (e.g., nylon) containing an aromatic bis-sulfonamide having at least two aromatic rings and from 14 to 30 carbon atoms in the molecule in quantity sufficient to improve the melt flow properties of the polymer. These sulfonamides are of advantage in that they have relatively low volatilities at polymer processing temperatures.

Aromatic bis sulfonamide-containing nylon or polyester

Described are thermoplastic polymer compositions (e.g., nylon) containing a polyhaloaromatic sulfonamide in quantity sufficient to improve the melt flow properties of the polymer. Such sulfonamides contain (a) from 7 to 30 carbon atoms, (b) from 2 to 12 chlorine and/or bromine atoms, (c) one nitrogen atom, (d) an aromatic group, bonded to the sulfur atom, in which at least two chlorine or at least two bromine atoms or at least one chlorine atom and at least one bromine atom are directly bonded to the aromatic ring system, and (e) one or two aliphatic, cycloaliphatic, or aromatic organic groups bonded to the nitrogen atom, one such organic group, when an aromatic group, optionally being substituted by one or more bromine and/or chlorine atoms. These sulfonamides are of advantage in that they have relatively low volatilities and good thermal stability at polymer processing temperatures and serve as flame retardants therein.

This invention relates to a compound of the formula, ##STR1## wherein: M is Sb(III) or Bi(III), x and y are whole integers and x=1, 2 or 3, y=0, 1 or 2 and x+y=3; each R is independently selected from hydroxy radicals, alkoxy radicals and phenoxy radicals; and each R' is independently selected from haloalkoxy radicals and halophenoxy radicals in which each halo constituent is independently selected from bromine or chlorine. Such compounds are useful flame retardants.
