    Abstract: A method of making a (meth)acrylate copolymer having pendent phosphate-containing groups and a pressure-sensitive adhesive that contains the (meth)acrylate copolymer having pendent phosphate-containing groups are provided. The method includes reacting a precursor (meth)acrylate copolymer having pendent carboxylic acid groups with an epoxy-functionalized phosphate compound. The pendent phosphate-containing groups on the reaction product can function as a flame retardant for the pressure-sensitive adhesive.

    Abstract: An adherable film includes a substrate that is substantially free of a flame retardant material and has a top major surface and a bottom major surface. An adhesive layer disposed on the bottom major surface of the substrate has a continuous pattern. The adhesive layer is made of an adhesive that is substantially free of a flame retardant material. In a plan view, the continuous pattern defines a plurality of discontinuous non-adhesive portions of the substrate without the adhesive. Each discontinuous non-adhesive portion is completely surrounded by the continuous pattern. The adherable film including the adhesive layer having the continuous pattern exhibits an improved flame retarding characteristic relative to a discontinuous adherable film having a substrate with a same material composition as that of the substrate of the adherable film and a discontinuous adhesive layer with a same material composition as that of the adhesive layer of the adherable film.
