✦ Synopsis

Abstract

The radical alternating copolymerization of N‐methylmaleimide with various olefins was carried out to obtain thermally stable and transparent polymers. Cyclic olefins including an exo‐methylene group showed high polymerization reactivities during the copolymerization. The introduction of a polar substituent into the olefin monomers results in the formation of copolymers with a high yield. The polymerization reactivity of the olefins is discussed based on DFT calculations. The introduction of cyclic and polar substituents into the olefin repeating units increased the glass transition temperature of the obtained copolymers, similar to the previously reported results for the introduction of bulkier and polar substituents into the N‐substituents of the maleimide.
