Outline of Final Research Achievements

Thermoplastic elastomers are expected materials due to their processability and recyclability because common elastomers chemically cross-linked needs energy and time for processing and are difficult to be recycled. In this study, we developed thermoplastic elastomers with high thermal stability from simple hydrocarbon monomers, propylene, 1-octene and norbornene, using a coordination polymerization catalyst which the authors have been developed by precisely controlling the polymer structures. The elastomers developed possessed (1-octene-stat-norbornene) sequences as a hard segment, of which glass transition temperature is controllable below 400 degree Celsius, and an atactic polypropylene sequence as a soft segment.
