Abstract
The maleimide copolymer of the invention is of the class of N-substituted maleimide copolymer such as N-alkyl or N-aromatic maleimide copolymer having peroxy bonds in a molecule, utilizable as a precursor for preparing a maleimide block copolymer and as a modifier for other resins. The maleimide block copolymer, which is useful as a molding material or a thermal resistance improver, is obtained by polymerizing maleimide monomers in the presence of a polymeric peroxide followed by polymerizing vinyl monomers.
