| 发明名称 | Chloroprene rubber composition and adhesive composition using said chloroprene rubber composition | ||
| 摘要 | An object of the invention is to provide a chloroprene polymer composition resistant to discoloration under heat or light. Provided is a chloroprene rubber composition, prepared by carrying out emulsion polymerization in the presence of 0.5 to 7.0 parts by mass of a rosin acid salt as emulsifier and terminating the emulsion polymerization by addition of a polymerization inhibitor and a phosphorus- or phenol-based compound as antioxidant. It is possible according to the invention to obtain a chloroprene polymer composition superior in discoloration resistance under heat or light. The chloroprene polymer composition according to the present invention can be used favorably for adhesion of cloths, leathers, foamed sheets, papers, woods, shoe parts, and others. | ||
