PURPOSE:To obtain a thermoplastic resin composition having excellent cleaning effect and suitable for the cleaning of a molding machine in the change-over of grades in plastic molding process, by compounding a neutral salt of an organic sulfonic acid and a powdery inorganic compound having specific particle diameter to a base resin. CONSTITUTION:A thermoplastic resin (e.g. polyethylene) is compounded with (A) 2-30wt% one or more sulfonic acid neutral salts selected from alkylbenzenesulfonic acid sodium salt having 6-20C alkyl group, alkylsulfonic acid sodium salt having 8-20C alkyl group and sodium salt of a sulfosuccinic acid diester of a 6-16C alcohol and (B) 0.05-5wt% powdery inorganic compound having particle diameter of 0.005-10mum (e.g. silicon dioxide, diatomaceous earth, etc.). |
