摘要
Polyimide addition copolymers of improved physical properties and thermal stability are prepared by reacting ethylenically unsaturated bis- imides with compounds having two methylene groups activated by adjacent carbonyl groups. The copolymers may be made in the presence of catalytic amounts of amines or with greater amounts of polyamines. The polymers are useful in producing molding powders, prepregs, laminates, circuit boards, encapsulants and metal clad shapes.
