Abstract: Thin walled products having good scratch resistance are disclosed, as are processes for making such products (e.g. films, sheets, and thin walled articles). The product includes a thin layer formed from (A) a cross-linkable polycarbonate resin having endcaps derived from a monohydroxybenzophenone; and (B) if desired, a base polymeric resin. When exposed to ultraviolet light, crosslinking will occur in the layer with the cross-linkable polycarbonate resin, enhancing the scratch resistance properties of the thin layer and the overall product.

Abstract: Polycarbonate articles having improved properties due to their substantially cross-linked nature are disclosed. The substantially cross-linked articles are formed by forming a product from a polymeric composition comprising a cross-linkable polycarbonate resin containing a photoactive group derived from a benzophenone, and exposing the formed product to an effective dosage of ultraviolet radiation to cause substantial cross-linking throughout the article. Such cross-linking can also be used to obtain films having good scratch resistance properties.
