Abstract:
A polyisocyanate curable graft copolymer emulsion having a weight average molecular weight of 3,000 to 65,000 which is anionically stabilized and which comprises:i) 20 to 95 weight percent of a polymer backbone of polymerized unsaturated compounds;ii) 5 to 80 weight percent of a macromonomer comprising at least about 5 weight percent of an unsaturated acid-functional monomer, said macromonomer prepared using a cobalt-based catalytic chain transfer agent and said macromonomer having a weight average molecular weight of about 1,000 to 30,000;in which the backbone comprises 0.5 to 30 weight percent, of total polymerizable unsaturated compounds, of an amino-functional polymerizable component.
