    摘要: Disclosed is a method of making an article, the method comprising: melt extruding a plurality of layers comprising one or more polymer compositions in a preset pattern, wherein the extruded layers comprise one or more first layers comprising a first polymer composition A, and one or more second layers comprising a second polymer composition B having a chemical composition different from the first polymer composition A, having a glass transition temperature (Tg) that is 5-100 degrees C. lower than polymer composition A, and which acts as a adhesion promotion layer between two layers comprising first polymer composition A; and fusing the plurality of layers to provide the article.
