概要	Itaconate-unit-containing poly(butylene succinate) (PBSI) was synthesized by the reaction of 1,4-butanediol, succinic acid, and itaconic acid in a molar ratio of 2.0 : 1.0 : 1.0, and the obtained PBSI was reacted with methacryl-group-substituted polysilsesquioxane (ME-PSQ) in the presence of benzoyl peroxide (BPO) at 130 degree C to produce PBSI/ME-PSQ hybrids. The hybrids showed a much higher thermal degradation temperature and storage modulus in the rubbery state than the cured PBSI (CPBSI). The thermal degradation temperature and storage modulus of the hybrids increased with increasing ME-PSQ content. The Tg of the hybrid composites, somewhat increased with increasing ME-PSQ content. However, the Tg's of all the hybrids were lower than that of C-PBSI. Although the IR absorption peak related to C=C groups was not detected for C-PBSI, some olefinic absorption peaks remained for all the hybrids.
