ABSTRACT:
A process for accelerating the cure rate of a thermoplastic composition comprising blending 5-95 parts by weight of a crystalline polyolefin resin of a substantially saturated homopolymer or copolymer of a C.sub.2 -C.sub.8 alpha monoolefin and 5-95 parts by weight of a crosslinkable ethylene-containing terpolymer comprising ethylene, an alkyl acrylate or alkyl methacrylate wherein the alkyl group contains 1-6 carbon atoms or a vinyl ester of a monocarboxylic acid having 2-6 carbon atoms, and glycidyl acrylate or glycidyl methacrylate, and mixing and shearing the composition while crosslinking the ethylene-containing terpolymer with a crosslinking agent that is a combination of (a) from about 1.5-9 parts by weight per 100 parts ethylene-containing terpolymer of an organic aliphatic or aromatic polycarboxylic acid or anhydride thereof containing 3-8 carbon atoms and (b) from about 0.3-8 parts by weight per 100 parts ethylene-containing terpolymer of a divalent tin halide salt or a stannous acylate having the formula ##STR1## where R is an aliphatic hydrocarbyl radical having from 1-18 carbon atoms.
