POLYMER COMPOSITION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a novel polymer composition formed of a polymethyl meth acrylate and maintaining transparency without turning yelloro when exposed to sterilizing radiant rays such asγ-rays or electron beams for the purpose of sterility. SOLUTION: This polymer composition is resistant to sterilizing radiant rays and comprises a) least 50% of one or more species of units derived from an alkyl methacrylate monomer and, if necessary, one or more species of monomers selected from vinyl and vinylidene monomers and b) 0.5-2 wt.% of at least one aliphatic alcohol (having<=10C) based on the monomer.
