Patent ID: 7344758

Claim:
A polymer extender composition comprising monomers copolymerized in the following percentages by weight: (a) from about 60% to about 94% of a monomer, or mixture of monomers, of the formula I: [CH 3 —(CH 2 ) p ][CH 3 (CH 2 ) n ]CHCH 2 —OC(O)—C(R)═CH 2 (I), and (b) from about 5% to about 20% of a monomer, or mixture of monomers, of the formula II: H—(OCH 2 CH 2 ) m —O—C(O)—C(R)═CH 2 (II) (c) from about 0% to about 3% of a monomer, or mixture of monomers, of the formula III: HO—CH 2 —NH—C(O)—C(R)═CH 2 (III) (d) from about 0% to about 20% of a monomer, or mixture of monomers, of formula IV: R 1 —OC(O)—C(R)═CH 2 (IV) (e) from about 0% to about 2% of ethylene dimethacrylate, and (f) from about 0% to about 10% of a monomer, or mixture of monomers, of formula (V): R f —CH 2 CH 2 —OC(O)—C(R)═CH 2 (V) wherein each R is independently H or CH 3 ; R 1 is an alkyl chain from 1 to about 18 carbon atoms; n is 1 to about 10; p is 1 to about 20 and m is 2 to about 10, and R f is a straight or branched-chain perfluoroalkyl group of from 2 to about 20 carbon atoms, or a mixture thereof.
