Abstract: Methods of grafting a liquid crystalline coating onto a substrate, and articles comprising a substrate with a liquid crystalline coating are disclosed. The liquid crystalline coatings can be formed by (a) applying a primer layer comprising a Type II photoinitiator to a surface of the substrate, then (b) applying a coating mixture that comprises one or more liquid crystalline monomers to the surface of the substrate, and then (c) irradiating the coating mixture to form the liquid crystalline coating. The coating mixture can further comprise a second amount of a Type II photoinitiator. The methods can be performed in open air, at room temperature, or at ambient pressure, and the resulting liquid crystalline coatings can exhibit improved adhesive properties to the substrate.

Abstract: A polycarbonate composition comprises: 30 to 95 wt % of one or more bisphenol A polycarbonate homopolymers; and 5 to 70 wt % of a poly(carbonate-siloxane) copolymer with a siloxane content of 10 wt. % to 25 wt. % based on the total weight of the poly(carbonate-siloxane), in an amount effective to provide a total siloxane content of 0.5 wt. % to 17.5 wt. % based on the total weight of the composition; the poly(carbonate-siloxane) copolymer comprising bisphenol carbonate units and siloxane units of the formulas or a combination comprising at least one of the foregoing, wherein E has an average value of 10 to 100, preferably 20 to 60, more preferably 30 to 50; wherein in the poly(carbonate-siloxane) copolymer less than 0.5 mol % of the siloxane units are directly coupled to another siloxane units.

Abstract: A polycarbonate composition comprises: a first poly(carbonate-siloxane) copolymer comprising carbonate units and siloxane units, wherein less than 0.5 mol % of the siloxane units are directly coupled to another siloxane unit; the first poly(carbonate-siloxane) copolymer comprising siloxane units with an average block length of about 10 to about 100, and a siloxane content from 5 wt % to 8 wt %; a second poly(carbonate-siloxane) copolymer comprising carbonate units and siloxane units, wherein less than 0.5 mol % of the siloxane units are directly coupled to another siloxane unit; the second poly(carbonate-siloxane) copolymer comprising siloxane units with an average block length of 10 to 100, a siloxane content from 10 wt % to 30 wt %, and wherein the weight ratio of the first poly(carbonate-siloxane) copolymer to the second poly(carbonate-siloxane) copolymer is 2 to 20; and optionally a bisphenol polycarbonate; wherein the polycarbonate composition has a total siloxane content of 2.5 wt % to 10 wt % and a molded part of 1 mm thickness has a haze of less than 2% as measured by HazeGard (ASTM D1003-00).
