PCT No. PCT/US95/15885 Sec. 371 Date Dec. 5, 1995 Sec. 102(e) Date Dec. 5, 1995 PCT Filed Dec. 5, 1995 PCT Pub. No. WO97/20832 PCT Pub. Date Jun. 12, 1997Isomaleimides 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.
