Fluoropolymers
The invention relates to novel linear, semi-crystalline fluoropolymers containing 0.5 to 25 mole percent of at least one vinyl ester monomer unit. At least 40 mole percent of the vinyl ester monomer units are present in the copolymer as single monomer units (not diads or triads or greater) between two fluoromonomer units. The invention also relates to a process for forming the fluoromonomers/vinyl ester copolymer. The fluoropolymer of the invention may be used in applications benefiting from a functional fluoropolymers including as a binder or coating in batteries, or for use in forming hydrophilic membranes and hollow fibers.

Aqueous dispersion of fluoroalkylated polymer particles with acorn morphology
The present invention provides a composition comprising 1) an aqueous dispersion of polymer particles having a core-shell morphology wherein the core protuberates from the shell; wherein the core comprises from 5 to 90 weight percent structural units of a fluoroalkylated monomer, and 2) less than 0.09 weight percent structural units of a phosphorus acid monomer; and wherein the shell comprises from 0.1 to 5 weight percent of itaconic acid or a phosphorus acid monomer, based on the weight of the shell. The present invention addresses a need in the art by providing a way of selectively concentrating fluoroalkyl functionality into polymer particles with acorn morphology, thereby providing an improvement in dirt pick-up resistance of the subsequent coating.
