MULTI-LAYER PRODUCT CONTAINING POLYCARBONATE

摘要

A multi-layer product comprising a coex layer and a base layer is disclosed. The coex layer contains a copolycarbonate derived from repeat units having the formula (I) where R1 to R4 are defined and repeat units having the formula (II) where R5 to R8 and X are defined. The base layer contains a polycarbonate characterized in that its chemical resistance is lesser than that of said copolycarbonate. The product is characterized by its improved resistance to chemical attack. Also disclosed are a uses of, and a method for producing the product.
