Patent ID: 7157526

Claim:
An aqueous primary dispersion that is substantially or completely free from volatile organic compounds comprising a polymer having a diameter≦500 nm comprising a controlled free-radical microemulsion or miniemulsion polymerization product of at least one olefinically unsaturated monomer in the presence of at least one hydrophobic additive and at least one oligomeric polyester with a number-average molecular weight of from 150 to 1500 daltons, a hydroxyl number of from 100 to 1000 mg KOH/g, and an acid number<20 mg KOH/g, wherein the polymer is at least one of a dispersed solid polymer particle, an emulsified solid polymer particle, a dispersed liquid polymer particle, an emulsified liquid polymer particle, or a dispersed solid core-shell particle, wherein the at least one hydrophobic additive comprises at least one polyhydroxy-functionalized alkane that is cyclic or acyclic and has 9 to 16 carbon atoms in the molecule.
