Abstract: In various embodiments, a method of making a molded article comprises forming a composite into a desired shape for the article, and cutting the formed article to form desired openings in the article. The composite comprises a top layer that comprises a blend of a first polycarbonate comprising repeat units of dimethyl bisphenol cyclohexane and a second polycarbonate comprising repeat units of bisphenol A, said second polycarbonate being different from said first polycarbonate, wherein the repeat units of dimethyl bisphenol cyclohexane are present in an amount of at least 50 weight percent relative of the total repeat units in the top layer, and (b) a second layer comprising a bisphenol-A polycarbonate, said second layer being joined with the top layer.

Abstract: Multi-layer composites having a blend of a dimethyl bisphenol cyclohexane polycarbonate and a bisphenol A polycarbonate as a top layer joined to a bisphenol-A polycarbonate second layer provide both surface scratch resistance and the ability to form molded and die cut articles. In the top layer, repeat units of dimethyl bisphenol cyclohexane are present in an amount of at least 50 weight percent relative of the total repeat units in the top layer, preferably in a weight ratio of from 60 to 75 weight percent.
