Abstract
A process can be used for manufacturing an acrylic copolymer having increased heat resistance, high transparency, and improved adhesion to metal surfaces. The process involves polymerizing a monomer mixture, optional heating of the copolymer mixture, and removing volatile components from the copolymer mixture by degassing. Moulding compositions containing this copolymer are highly suitable for manufacturing optical elements for optoelectronic devices containing acrylic and metallic or ceramic parts.
