Title:
METHOD FOR PRODUCING ACRYLIC RUBBER
Document Type and Number:
WIPO Patent Application WO/2018/079785
Kind Code:
A1
Abstract:
Provided is a method for producing an acrylic rubber, the method being provided with: an emulsion polymerization step for obtaining an emulsified polymer solution by emulsion-polymerizing a monomer in the presence of a nonionic emulsifier and an anionic emulsifier, the monomer being a monomer for forming the acrylic rubber; and a coagulation step for obtaining a water-containing crumb rubber by adding a coagulating agent to the emulsified polymer solution to be coagulated. According to the present invention, a method for producing an acrylic rubber may be provided, wherein the occurrence of the contamination of a polymerization device during polymerization can be suitably suppressed, and the occurrence of mutual adhesion of water-containing crumb rubbers can be effectively prevented.
