TRIBLOCK COPOLYMER AND METHOD FOR PRODUCING TRIBLOCK COPOLYMER

摘要

The triblock copolymer according to one embodiment of the present invention is an A-B-A type triblock copolymer that comprises polymer block A constituting a hard segment having a glass transition temperature of 80-150°C and polymer block B constituting a soft segment having a glass transition temperature of 25°C or lower, wherein, when the storage elastic modulus is measured under conditions of a temperature rising rate of 5°C/min and a frequency of 1 Hz, a rubbery plateau area is observed in a temperature range exceeding the glass transition temperature of the hard segment.
