ABSTRACT:
A high temperature heat resistant methacrylate-maleimide copolymer having at least 90% by weight methyl methacrylate monomer and up to about 10% by weight maleimide monomer to form a clear, weather-resistant copolymer having glass transition temperatures from about 105.degree. C. to about 131.degree. C. and a method of manufacture of the copolymers through an extremely high conversion bulk polymerization process.
