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. 公开了种制造塑料制品的方法。根据这种方法，塑料制品由包含第聚合物组分的热塑性组合物形成，第聚合物组分是(i)聚(硅氧烷-碳酸酯)共聚物，(ii)具有软嵌段酯单元的聚(脂肪族酯)-聚碳酸酯，衍生自包含α,ωC脂肪族二羧酸或其衍生物、二羟基芳香族化合物和碳酸酯源的单体，(iii)热塑性聚氨酯，(iv)热塑性聚氨酯，或包含任何前述物质的组合。然后通过使制品的表面与超临界流体二氧化碳接触而将诸如光致变色染料的添加剂载入塑料制品中，超临界流体二氧化碳包含溶解或分
