METHOD FOR PRODUCING (METH)ACRYLIC RESIN

Document Type and Number:

WIPO Patent Application WO/2016/052600

Kind Code:

A1

Abstract:

Provided is a method for inexpensively producing a (meth)acrylic resin by maintaining high transparency in production over an extended period of time by a polymerization reactor. A (meth)acrylic resin is obtained by a method including storing a thiol chain transfer agent in a tank comprising austenitic stainless steel having an Mo content of 0.5-7.0 mass%, transferring the thiol chain transfer agent to a polymerization reactor comprising austenitic stainless steel having an Mo content of 0.5-7.0 mass% through a conduit comprising austenitic stainless steel having an Mo content of 0.5-7.0 mass%, radical-polymerizing methyl methacrylate in this polymerization reactor, and removing the unreacted material from the resulting reaction product.
