摘要： The present invention comprises a composition and method of use for providing cleanability to paint comprising an aqueous emulsion of Formula (I) wherein the composition of Formula (I) is a random copolymer; wherein said composition of formula (I) further comprises residue from a hydrophilic chain transfer agent. The compositions of the present invention provide durability to coating compositions, while also providing surface effects such as increased water and oil contact angles, enhanced dirt pickup resistance, and enhanced cleanability to the coating films. For these reasons, the composition of the present invention is particularly suitable for use as additives to exterior coatings and paints.
