METHOD FOR PRODUCING VINYL CHLORIDE-BASED RESIN PASTE HAVING REDUCED CHANGE OF ELAPSED TIME IN VISCOSITY

摘要

PURPOSE: A producing method of a vinyl chloride-based paste resin is provided to improve the processing ability of plastisol by additionally inserting a nonionic emulsifier. CONSTITUTION: A producing method of a vinyl chloride-based paste resin comprises the following steps: inserting a nonionic emulsifier to vinyl chloride-based latex obtained by the emulsion polymerization; and drying the outcome to obtain vinyl chloride-based paste. The emulsion polymerization for the vinyl chloride-based latex uses seeds having to different sizes.
