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.
