| 摘要 |
A crystalline block copolymer containing at least a triblock or at least a radial structure and a process for producing the same, wherein at least one block comprising a vinyl aromatic compound having a glass transition temperature (Tg) of not lower than 50 DEG C., at least one block comprising a conjugated diene polymer having a 1,4-trans linkage content, a Tg not higher than 10 DEG C. and crystallinity at 25 DEG C. and in which the crystalline block copolymer optionally which contains the radial structure further comprises a coupling agent. The polymer or the composition containing the same can be utilized for fixing materials of affected portions for medical purposes, protector materials for various sports, films, laminates, toys, artificial flowers, heat-sensitive sensors, coupling devices, insulating materials, framework materials, etc.
