Outline of Final Research Achievements

Multicyclic polymers are categorized into three basic polymer topologies of fused, spiro and bridged shapes. A double-eight structure that is a novel multicyclic polymer topology with combined two basic structures of spiro and bridged shapes was synthesized. An 8-shaped telechelics having an ethynyl group was synthesized by using the ESA CF process. A click reaction between this telechelics and linear telechelics having azido end groups resulted in the formation of a double-eight polymer. Characterization was performed by 1H NMR, SEC and MALDI TOF MS, The crude product was subjected to the fractionation by means of a preparative SEC technique.
