METHACRYLIC RESIN AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a methacrylic resin containing 80-98.5 wt% of a methyl methacrylate monomer unit and 1.5-20 wt% of another vinyl monomer unit which is copolymerizable with at least one methyl methacrylate. This methacrylic resin is characterized by having a weight average molecular weight determined by gel permeation chromatography (GPC) of 60,000-230,000. The methacrylic resin is also characterized in that a component having a weight average molecular weight of not more than 1/5 the peak weight average molecular weight (Mp) obtained from the GPC elution curve is contained in an amount of 7-30% relative to the methacrylic resin component.
