    Abstract: Acrylic copolymer solutions having a Tg less than O"C., a weight average molecular size ranging from about 20,000 to about 50,000 and consisting essentially of about 4-14% ethylenically unsaturated acid, about 80-95% methyl acrylate and/or ethyl acrylate and about 1-8% lower alkyl methacrylate are obtained by copolymerizing the comonomers in the presence of * an organic solvent which functions as a chain terminator. Water-borne, heatcurable, internal can coating compositions may be prepared by formulating these acrylic copolymer solutions with aqueous ammonia and a water-dispersible, cross-linking reagent.
