PHOTOPOL YMERIZA TION OF MALEIMIDE ANDITS N-SUBSTITUTED DERIVATIVES

To the best knowledge of the present authors, the photopolymerization of maleimide and its N-substituted derivatives has not so far been reported. We found that the photopolymerization of these monomers proceeds without the sensitizer under various conditions. This communication is concerned with the results of polymerization in both the solid state and the solution. It is emphasized that some kinds of the polymers obtained have crystlalline structures
