Abstract: Poly(vinyl chloride), when impact modified with a core/shell acrylic impact modifier whose shell is predominantly formed from 50-90 parts of polymerized units of methyl methacrylate and 10-50 parts of polymeric units of a C.sub.2 -C.sub.8 alkyl acrylate and whose core is a crosslinked copolymer mainly of polymeric units of butyl acrylate, exhibits improved fusion behavior, allowing conversion to an intimate, fused, processable blend at lower temperatures and faster rates, than when the shell of the impact modifier is substantially formed from methyl methacrylate alone.

Abstract: The invention relates to improved polyacetal compositions composed of polyoxymethylene (component A) and a stabilized MBS core shell graft copolymer (component B) formed from a rubber-elastic core based on polybutadiene, and a hard graft shell.The stabilized MBS core shell graft copolymer (component B) contains a special stabilization formulation of at least one hindered phenol, a phosphite, a sulfide, and a pH buffer system.The shaped articles produced from these mixtures are particularly distinguished by an excellent low-temperature impact strength and a good heat aging performance.

Abstract: A miscible blend of two acrylic polymers, one of which contains a poly(1,2 -alkyleneoxy) side chain, with a soluble lithium salt yields a conducting polymer system useful in small rechargeable batteries without the need for volatile polar solvents. By employing one polymer with a glass temperature below 35.degree. C. in conjunction with control of molecular weight of both components, a flexible film may be formed by conventional thermoplastic methods. The conductive salt, preferably LiN(CF.sub.3 SO.sub.2).sub.2), may be incorporated during the polymerization which forms the acrylic polymers.
