1. 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;


    [CH3

    (CH2)p][CH3(CH2)n]CHCH2

    OC(O)—

    C(R)═

    CH2



    (I), and(b) from about 5% to about 20% of a monomer, or mixture of monomers, of the formula II;


    H—

    (OCH2CH2)m

    O—

    C(O)—

    C(R)═

    CH2



    (II)(c) from about 0% to about 3% of a monomer, or mixture of monomers, of the formula III;


    HO—

    CH2

    NH—

    C(O)—

    C(R)═

    CH2



    (III)(d) from about 0% to about 20% of a monomer, or mixture of monomers, of formula IV;


    R1

    OC(O)—

    C(R)═

    CH2



    (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);


    Rf

    CH2CH2

    OC(O)—

    C(R)═

    CH2



    (V)whereineach R is independently H or CH3;

    R1 is an alkyl chain from 1 to about 18 carbon atoms;

    n is 1 to about 10;

    p is 1 to about 20 andm is 2 to about 10, andRf is a straight or branched-chain perfluoroalkyl group of from 2 to about 20 carbon atoms, or a mixture thereof.
