Method for producing thermoplastic elastomer powder

Abstract

A method for producing powder of a thermoplastic elastomer having a sphere-reduced average particle diameter of 700 μm or less by an under water cut method which comprises discharging the thermoplastic elastomer in melt state through a plurality of orifice in a dice in into water, and cutting the discharged matter with a cutter blade rotating along the dice surface to obtain powder of the thermoplastic elastomer, wherein the method satisfies the following conditions (a) and (b): (a) the temperature of the thermoplastic elastomer directly before the dice is from 120 to 220° C., and (b) the temperature of a dice is from 230 to 350° C.
