  • 1,1-substituted arylethylenes/polymaleimide copolymers
    Patent number: 5134214
    Abstract: Copolymers comprising, in polymerized form, a 1,1-substituted arylethylene comonomer and at least one polymaleimide comonomer, are prepared using a system that provides a reduced onset of polymerization temperature thereby allowing removal of the copolymer from the mold after a preliminary curing period followed by transfer to an oven, a less expensive piece of equipment, for additional curing; thus making the mold, a more expensive piece of equipment, available for the next polymerization run.
