ABSTRACT:
This invention relates to emulsion-type adhesive compositions which include a copolymer of a conjugated diene and sulfopropyl-N-methacroyloxyethyl-N,N-dimethyl ammonium betaine, wherein the sulfobetaine copolymer has about 0.15 to about 15 mole % sulfobetaine groups per 100 grams of the neutralized sulfonated copolymer, and less than about 250 parts by weight of a hydrocarbon resin of a petroleum or coal tar distillate, having about 5 to 6 carbon atoms, the hydrocarbon resin being composed of aliphatic dienes and mono-olefins per 100 parts by weight of the neutralized sulfonated copolymer.
