METHOD FOR PRODUCING THERMOPLASTIC ELASTOMER PELLET

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a thermoplastic elastomer pellet which has an excellent antiblocking effect and is pelletized in an excellent state.SOLUTION: The method for producing the thermoplastic elastomer pellet, which pellet is a polymer containing a vinyl aromatic hydrocarbon monomer unit and a conjugated diene monomer unit or a hydrogenated product thereof, comprises: a step (1) of hot-cutting a thermoplastic elastomer; a step (2) of adding 0.001-0.5 pts. mass of an antiblocking agent A to 100 pts. mass of the thermoplastic elastomer; a step (3) of cracking the resulting thermoplastic elastomer; a step (4) of drying the cracked thermoplastic elastomer; and a step (5) of adding 0.01-2.0 pts. mass of another antiblocking agent B to 100 pts. mass of the dried thermoplastic elastomer.
