| Outline of Final Research Achievements |
This study aimed to develop the concurrent vinyl-addition and ring-opening cationic copolymerization of vinyl and cyclic monomers. Meaningful results were obtained in the following seven topics: (1) the copolymerization of vinyl ethers and oxiranes having suitable substituents, (2) the copolymerization using β-methyl-substituted glycidyl ethers, (3) frequency control of crossover reactions in the concurrent vinyl-addition and ring-opening cationic copolymerization, (4) one-way cycle of sequence control by vinyl-addition, ring-opening, and carbonyl-addition terpolymerization, (5) copolymerization of alkoxyoxirane and vinyl ether via the alkoxy group transfer mechanism, (6) controlled copolymerization of vinyl monomers and cyclic acetals, and (7) vinyl-addition and coordination ring-opening copolymerization of vinyl ethers and cyclic esters.
