发明名称 Method for making multilayered resin bodies having UV-protection and the resultant products
摘要 A method for making multilayered synthetic resin bodies by the coextrusion of thermoplastic molding compounds wherein at least one of the layers in the extruded body is to be protected against UV light, which comprises extruding at least one layer from a thermoplastic molding compound that is formed entirely or predominantly of a copolymer formed between monomers comprising in their molecules groups or structures which, because of their characteristic absorption of ultraviolet light, provide protection against ultraviolet light, together with other, known, monomers.
