Abstract: Thermoplastic recording member in which a thermoplastic film recording layer is formed on a conductive support with the optional provision of an intermediate photoconductive layer, the resin film containing from 0.1 to 10% by weight of a silicone, fluorocarbon or chlorofluorocarbon oil, based on the weight of the film.

Abstract: Polymer alloys of a phosphorus-containing polymer component having the formula: ##STR1## WHEREIN X is hydrogen or halo; Z and Z' are each hydrogen or a phosphonate group PO(OR)(OR.sub.1) in which R and R.sub.1 are each alkyl or aryl, but are not both hydrogen, Y is a bivalent radical from an ethylenically unsaturated monomer copolymerized with styrene, and m, m', n, n' and p are zero or integers as specified; and a second polymer component compatible with and alloyed with the phosphorus-containing polymer component, the second component being a cellulose ester, or a polystyrene or unsaturated polyester resin. Polymer alloys thus constituted are particularly useful as fire-retardant and flame-resistant materials, and as membranes useful in the separation of solvents exhibiting differential permeabilities therethrough.

Abstract: Novel redox diphenoquinone-diphenohydroquinone polymers and derivatives thereof are described. The novel redox polymers are useful as oxidizing and reducing agents, antioxidants, stabilizers in dielectric compositions, semiconductor polymeric ingredients as well as redox ion exchange resins.
