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.

Abstract: A coated thermoplastic film can be subjected to printing to obtain a decorative film, preformed (for example, thermoformed), and then inserted into a mold that has the configuration of the preformed decorative film A base polymeric structure comprising a polymer such as a polycarbonate or blend thereof can be injection molded to the exposed surface of the preformed decorative film The molded structure has various applications such as cell phones or other electronic devices, automotive vehicles, appliances, display panels, lenses, etc. A process for making the molded article is also described. The coating for the coated thermoplastic film can be made from a UV-curable composition and can provide superior embossing and thermoformability, hardness, and adhesion, while providing enhanced chemical, scratch and abrasion resistance.

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: A halogen-free electrically insulating film is prepared from a composition including particular amounts of a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and a triaryl phosphate. The electrically insulating film may be prepared by an extrusion and/or calendering method. Uses of the electrically insulating film include, for example, shielding applications in power supply housing, printed circuit board insulation, backlit aircraft in flight panels and displays, business equipment insulation, computer rack partitions, and television and monitor insulation.

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.

Abstract: A repositionable and substantially transparent multi-layer anti-frost film assembly comprising a film and an anti-frost layer formed from a polyurethane-film forming composition effective to provide the layer with anti-frost properties at temperatures that alternate between ?23° C. and 65° C. Optionally, an anti-frost film assembly comprises an adhesive layer. The anti-frost film assembly to be applied with any of a variety of substantially transparent substrates to provide condensation-resistant articles, including refrigerator doors and panels.

Abstract: A composite film is disclosed, comprising a protective layer comprising an adhesion-modified polyolefin film, a coating layer comprising the reaction product of a crosslinkable compound, an initiator, and a binder; and a polycarbonate layer; wherein the coating layer is disposed between the protective layer and the polycarbonate layer, and the peel strength between the protective layer and the polycarbonate layer, as measured both before and after thermal treatment or a combination of thermal and UV treatment of the composite film, is about 1 to about 20 centi-Newtons per centimeter measured using 180° angle peel measured at a peel rate of 25.4 cm/min. A method for forming a composite film, and an article comprising the composite film, are also disclosed.
