Title:
CHLOROPRENE RUBBER COMPOSITION AND ADHESIVE COMPOSITION USING SAID CHLOROPRENE RUBBER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2013/121960
Kind Code:
A1
Abstract:
The present invention provides a chloroprene polymer composition that is less prone to discoloration even when exposed to heat and light. Provided is a chloroprene rubber composition obtained by: performing emulsion polymerization in the presence of 0.5-7.0 parts by mass of a rosin acid salt as an emulsifier; and terminating the emulsion polymerization by adding a polymerization inhibitor and also a phosphorus-based compound or a phenol-based compound as an antioxidant. With the present invention, it is possible to obtain a chloroprene polymer composition having excellent discoloration resistance to heat and light. Thus, this chloroprene polymer composition can be used suitably as an adhesive used for cloth materials, leather materials, foamed sheets, paper materials, wood materials, shoe parts, and the like.
