Abstract:
The present invention is a polymer latex that includes polymer particles having a core portion and a shell portion. The core portion contains polymerized hydrophobic ethylenically unsaturated monomers with a water solubility less than 1% at room temperature. The shell portion contains polymerized monomers defined by formula (I) wherein X is O or NH, or NCH3, R1 and R2 are H, CH3, C2H5, C3H7, or C4H9, R3 and R4 are H or CH3, n1 and n2 are integers, n1 is from 1 to 4, n2 is from 1 to 20. The polymer particles having a size of less than 50 nm.
