Abstract: Disclosed is a formable thermoplastic multi-layer article comprising an outer layer comprising a polymer comprising resorcinol arylate polyester chain members, a middle layer comprising a thermoplastic polymer, an inner tie-layer comprising a thermoplastic polymer comprising a carbonate polymer and bulk polymerized acrylonitrile-butadiene-styrene (ABS), the middle layer being between the outer layer and the inner tie-layer and being in contact with both the outer layer and the inner tie-layer. Also disclosed is a thermoformed multi-layer article. A method of making the article is also disclosed.

Abstract: One method for making a laminate material comprising a first surface layer comprising resorcinol arylate polyester chain members and a second surface layer suitable for bonding to a substrate, comprises co-extruding a polymeric first surface layer material and a polymeric second surface layer material through a die and into the first nip of a calender roll stack comprising a first surface roll and a second surface roll that define the first nip, to form the laminate material. A nip load in the first nip of greater than or equal to about 400 N/cm can be applied to the laminate, and the laminate material can be collected from the roll stack. The first roll and the second roll can each have a surface smoothness of less than or equal to about 5 micrometers and temperatures of about 40° C. to about 150° C.

Abstract: A method of forming a multilayer film is disclosed, comprising coextruding a first layer comprising a weatherable composition, and a second layer comprising a polycarbonate composition comprising a visual effect filler, wherein the first and second layers are formed by flowing each of the weatherable composition and polycarbonate composition through separate flow channels in a multi-manifold coextrusion die. The shear stress during extrusion on the polycarbonate composition is greater than or equal to 40 kilo-Pascals.
