Outline of Final Research Achievements

In order to design polymer materials that have both the high transparency, high toughness, and ease processing of vinyl polymers and the heat resistance and high strength of polycondensation and thermosetting resins, we have proposed a new method of polymer synthesis as the fusion of chain radical polymerization and stepwise addition. Utilizing a precisely controlled radical polymerization technique capable of sequence control, a reactive functional group is introduced into the polymer, and a precise network structure is formed by the use of the post-polymerization reaction and cross-linking to provide super heat-resistant polymer materials.
