PRODUCTION OF THERMOPLASTIC RESIN GRANULE

摘要

PROBLEM TO BE SOLVED: To provide a granular thermoplastic resin having high bulk density. SOLUTION: A powdery raw material of a thermoplastic resin produced by the polymerization of plural kinds of raw materials followed by the drying of the produced polymer is compression-molded at >=40 deg.C between a pair of rolls parallelly arranged interposing a narrow gap and the molded product is disintegrated to granules having diameter of <=10 mm.
