Abstract: Coating compositions comprising intimate blends of a pigment and an interpolymer of monovinyl aromatic monomer, allylic alcohol and optionally allylic ester, wherein the weight ratio of pigment to interpolymer is in the range of about 2:1 to about 10:1. The compositions are useful for the preparation of electrographic recording materials.

Abstract: A marine antifouling coating composition comprises an acrylic resin such as methyl methacrylate in the range of from 6 to 20% by weight, a polysiloxane having substituted thereon tributyltin moieties that are toxic to marine organisms. The polysiloxane is in the range of from 7 to 25% by weight. The acrylic resin and polysiloxane are dissolved in a solvent in the range of from 18 to 52% by weight with the balance of the composition in the range of from 10 to 65% by weight being primarily conventional marine paint and toxicant agents for augmenting action of the tributyltin polysiloxane. Copper or copper salts that are effective for inhibiting growth of marine organisms and facilitating release of toxins can also be included.

Abstract: A poly(arylene sulfide) polymer is cured in the presence of an ozone containing gas thereby reducing the time required for the curing process.

Abstract: A process is disclosed for the preparation of chlorinated poly(vinyl chloride), (hereinafter "CPVC" for brevity), in the form of free-flowing macrogranules which are derived from solid free-flowing macrogranules of poly(vinyl chloride), (hereinafter "PVC" for brevity), by causing from about 0.6 to about 3.0 parts by weight (wt) of liquid chlorine which are absorbed perunit wt of solid PVC macrogranules to react with the PVC, without shedding reacted material from the macrogranules. The macrogranules of PVC containing absorbed liquid chlorine held therewithin, are maintained in a wetted but free-flowing, apparently dry reaction mass (due to which the process is referred to as "the relatively dry chlorination" or "the low liquid chlorine" process), in a reaction zone maintained at a temperature in the range from about -50.degree. C. to about 50.degree. C., and a pressure sufficient to maintain the chlorine in its liquid state.

Abstract: Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic radicals or carboxy-functional organic radicals or epoxy-functional radicals and the other bearing another type of organofunctional radicals selected from the same group. In addition, at least one of the organofunctional polysiloxanes bears one or more polyoxyalkylene radicals.These compositions are useful for durably treating fibers to provide several benefits such as antistatic character, moisture/perspiration absorbability, stain resistance, pliability, smoothness, crease resistance and compression recovery.
