摘要： A method of making a plastic article is disclosed. According to this method, a plastic article is formed from a thermoplastic composition that includes a first polymer component that is (i) a poly(siloxane-carbonate) copolymer, (ii) a poly(aliphatic ester)-polycarbonate having soft block ester units, derived from monomers including an alpha, omega C6-20 aliphatic dicarboxylic acid or derivative thereof, a dihydroxyaromatic compound, and a carbonate source, (iii) a thermoplastic polyurethane, (iv) a thermoplastic polyurethane, or a combination comprising any of the foregoing. An additive such as a photochromic dye is then loaded into the plastic article by contacting a surface of the article with supercritical fluid carbon dioxide comprising the additive dissolved or dispersed therein.
