Abstract:
1. A process to produce a pre-emulsion, said process comprising contacting at least one fluoroalkyl monomer, at least one nonionic water-dispersible polyester, water, and optionally at least one ethylenically unsaturated monomer, wherein the amount of said fluoroalkyl monomer is that which is sufficient to produce a polymer containing from about 50 to about 100 weight percent fluoroalkyl monomer repeating units based on the total weight of monomer utilized; wherein the fluoroalkyl monomer is represented by the formula Rf-Q-OCOCR═CH 2 ; wherein Q is a bivalent organic group, R is a hydrogen atom or methyl group; wherein Q is selected from the group consisting of —(CH 2 ) p+q —; —(CH 2 ) p CONH(CH 2 ) q —; —(CH 2 ) p OCONH(CH 2 ) q —; —(CH 2 ) p SO 2 NR′(CH 2 ) q —; —(CH 2 ) p NHCONH(CH 2 ) q —; or —(CH 2 ) p CHOH—(CH 2 ) q —; wherein R′ is a hydrogen or an alkyl group, and each of p and q is an integer of at least 0, provided that p+q is an integer of from 1 to 22.
