Abstract

PURPOSE: To provide the titled processing assistant composed of a polymer of methyl methacrylate and other vinyl monomer and produced by the emulsion polymerization in the presence of a specific emulsifier, and effective in preventing the problems such as thermal discoloration in molding by compounding to a thermoplastic resin.
CONSTITUTION: The objective processing assistant is composed of a copolymer having a reduced viscosity of 2W0.1, preferably 1.5W0.1 (at 25°C) and produced by the emulsion polymerization of (A) 35W99.9wt% methyl methacrylate unit and (B) 0.1W65wt% other vinyl monomer unit copolymerizable with the monomer A (e.g. ethyl acrylate, styrene, etc.) in the presence of (C) an emulsifier of formula (R is 10W24C, preferably 12W18C alkyl or alkenyl; M is Na or K) and a polymerization initiator (e.g. sodium persulfate). 0.1W40pts.wt. of the processing assistant is added to 100pts.wt. of a thermoplastic resin (e.g. vinyl chloride resin, acrylonitrile-styrene resin, methyl methacrylate-styrene resin, etc.).
