    摘要: Isomaleimides and polyisomaleimides can be prepared by a method comprising the steps in sequence: admixing a maleamic acid or polymaleamic acid with an acid halide, reacting the admixture with a tertiary amine at a temperature sufficiently low to suppress the formation of a maleimide, and isolating the resulting isomaleimide or polyisomaleimide. Polymerization of a polyisomaleimide with a polynucleophilic monomer (polythiol, polyol, polyamine) produces novel polymers.

    摘要: Epoxy reactive liquid modifiers include acrylate functionalized compounds, acrylamide functionalized compounds, oxalic amide functionalized compounds, actoacetoxy functionalized urethanes and acetoacetoxy functionalized polyalkenes. The reactive liquid modifiers are incorporated into epoxy resin compositions comprising a curable epoxy resin, an amine curing agent, and the reactive liquid modifier, wherein the reactive liquid modifier is polymerized to form at least one of an interpenetrating polymer network and a semi-interpenetrating polymer network with the curable epoxy resin.
