    摘要: A process for forming an elastomeric polymer gel composition includes forming a blend by combining a poly(alkenyl-co-maleimide) that includes a maleimide and at least one monomer contributed unit derived from vinyl aromatic hydrocarbons, R1R2 ethylenes, and alkyl vinyl ethers; with a maleated polyalkylene. This is followed by addition of a crosslinking agent, which is allowed to react with the poly(alkenyl-co-maleimide) and maleated polyalkylene to form a polyalkyenyl grafted poly(alkenyl-co-maleimide). The polyalkenyl grafted poly(alkenyl-co-maleimide) is further blended with a polyester.
