摘要:
The present application is a composition including abase resin comprising between about 4% and about 15% acrylic acid monomer and an oligomer additive comprising (a) one of an acrylamide or meth(acrylamide) copolymer and (b) a high glass transition temperature monomer. The oligomer additive has a molecular weight range of between about 20,000 and about 1,000,000 and a glass transition temperature of between about 70° C. and about 115° C. The composition has a blending ratio of base resin to oligomer additive of between about 7 to about 30 parts per hundred of resin.
