Method for producing thermoplastic elastomer composition |
摘要 |
Provided is a method for producing a thermoplastic elastomer composition excellent in flexibility, mechanical properties and extrusion moldability which comprises directly feeding a particulate olefinic copolymer rubber (A) having a particle shape index (alpha) defined below of 0.1-0.9 and an olefinic plastic (B) to a continuous kneading extruder to carry out melt kneading and then, feeding an organic peroxide to downstream side of said extruder to carry out dynamic crosslinking: (alpha)=DA/DB wherein DA denotes bulk density of the particulate olefinic copolymer rubber (A) and DB denotes bulk density of the olefinic plastic (B).
