Abstract: A multilayer film comprising a superstrate, and a tie layer comprising a tie layer composition comprising a polycarbonate and a poly(alkylene ester) is disclosed, wherein a substrate contacted to the tie layer opposite the superstrate has initiation peel strength between the tie layer and the substrate of about 20 to about 60 pounds per linear inch (about 3,500 to about 10,500 Newtons per meter), measured at a 90° peel angle and a peel rate of 12.7 cm/min. An article comprising the multilayer film is disclosed. Methods of forming the multilayer film and the article are 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.
