Patent ID: 7598303

Claim:
A process for forming an aqueous dispersion having at least two polymeric components, comprising: (i) forming at least one high molecular weight polymeric component; and, (ii) forming at least one low molecular weight polymeric component according to formula I: A-B (I) wherein A is derived from a chain transfer component that exhibits a water solubility at 25 to 50° C. of no greater than 150 millimoles/liter and B is a polymer chain; wherein the low molecular weight polymeric component is formed in the presence of a macromolecular organic compound having a hydrophobic cavity selected from cyclodextrin, cyclodextrin derivatives, cyclic oligosaccharides having a hydrophobic cavity, calyxarenes, cavitands and combinations thereof; wherein the low molecular weight component is formed within the high molecular weight polymeric component; wherein the low molecular weight polymeric component exhibits a number average molecular weight of no more than 10,000 and the high molecular weight polymeric component exhibits a number average molecular weight of at least 50,000.
