ABSTRACT:
Thermally stable bisimido polymers, devoid of diamine component and well adapted for the production of laminates, are prepared by copolymerizing (a) an N,N'-bismaleimide with (b) an acrylate comonomer, e.g., a novolak epoxy (meth)acrylate, in the presence of a catalytically effective amount of (c) an imidazole compound, and, optionally, (d) a chlorinated or brominated epoxy resin, or admixture thereof with a non-chlorinated or non-brominated epoxy resin.
