METHACRYLIC RESIN COMPOSITION AND METHOD FOR PRODUCING ITS MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a methacrylic resin composition excellent in mold releasability at high temperature, hardly staining the mold even if the mold is repeatedly used, excellent in transparency and hardly providing defects in appearance. SOLUTION: This methacrylic resin composition is obtained by adding 0.001-0.05 pts.wt. 2-ethylhexyl acid phosphate and 0.002-0.1 pts.wt. ester salt of sulfosuccinic acid to 100 pts.wt. polymer composed of 60-100 wt.% methyl methacrylate monomer unit and 40-0 wt.% other copolymerizable vinylic monomer unit.
