Abstract
PURPOSE: The titled resin having a residual monomer content and a melt index both lower than specified values and excellent heat distorsion resistance and water resistance, prepared by copolymerizing a mixture containing methyl methacrylate, maleic anhydride and styrene in a specified ratio.
CONSTITUTION: A methacrylic resin comprising a copolymer which is prepared by polymerizing a monomer mixture consisting of (A) 36W98.4wt% methyl methacrylate, (B) 1W40wt% maleic anhydride and (C) 0.6W64wt% styrene, wherein said component C being present in an amount of at least 60wt%, based on said component B, and which has residual monomer content of below 1.5wt% based on the copolymer and a melt index of below 10g/10min. Marked improvement of heat distorsion resistance is attained by adding components B and C present in the above-specified ratio, to component A and copolymerizing the mixture.
