Abstract:
1. A polymer composition consisting essentially of monomers copolymerized in the following percentages by weight: (a) from about 5% to about 90% of a monomer of the formula I: (b) from about 5% to about 85% of vinylidene chloride, vinyl chloride, vinyl acetate, or a mixture thereof, (c) from about 0.5% to about 3% of a monomer of the formula II: (d) from about 0.5% to about 3% of a monomer of the formula III and (e) from about 1% to about 5% of a monomer of the formula IV: (f) from 0% to about 25% of methyl methacrylate, vinylbenzyl chloride, styrene or a mixture thereof, wherein said composition increasing fluorine efficiency in treatment of a substrate by permitting use of lower levels of fluorinated surface treating agents providing durable oil repellency and water repellency, such that the fluorine content of a blend of said composition with a fluorinated surface treating agent is from about 1.5% to about 6.6% by weight of the blend.
