Patent ID: 8519026

Claim:
A polymeric composition for making aqueous polymeric dispersions, said polymeric composition comprising hydrophilic macromonomer (I), hydrophobic polymer (II) and bridging monomer (III), wherein the hydrophilic macromonomer (I) and hydrophobic polymer (II) are grafted together in the presence of bridging monomer (III); the hydrophilic macromonomer (I) has a structure according to formula (1): R—C(X)═CH 2 , wherein R is a polymeric group and X is a radical stabilizing group; and the hydrophobic polymer (II) is an alkyd, a polyester, a melamine, a polyurethane, a polyepoxide, a polyisocyanate or a polysiloxane, comprising an ethylenically unsaturated bond, or hybrids or mixtures thereof, and has a number average molecular weight ranging between 500 and 250000.
