| Outline of Final Research Achievements |
To prepare various stimuli-responsive block or alternating polymer materials, the authors developed new methods via living/controlled cationic polymerization such as base-assisting living cationic polymerization and the alternating cationic copolymerization of vinyl ethers with conjugated/aromatic aldehydes as follows; (1) highly stereospecific living cationic polymerization of N-vinylcarbazole as a result of the elaborate design of counteranions using an initiating system, (2) sequence-controlled polymers with precisely placed breakable bonds in the main chain, and unique tandem reactions of sequence-controlled cationic copolymerization and site-specific hetero Diels-Alder reaction, (3) synthesis of various stimuli-responsive block or star-shaped copolymers: block copolymers with UCST-type segment and LCST-type segment exhibiting shape-switching self-assembly in water, quantitative and ultrafast synthesis of well-defined star-shaped polystyrenes.
