Abstract
Polar polymers having the following formula: EQU FG-(Q).sub.d -R.sub.n -Z-J-[A(R.sup.1 R.sup.2 R.sup.3)].sub.x (I) wherein FG is H or a protected or non-protected functional group; Q is a polar hydrocarbyl group derived by incorporation of a polar compound selected from group consisting of esters, amides, and nitrites of acrylic and methacrylic acid, and mixtures thereof; d is an integer from 10 to 2000; R is a saturated or unsaturated hydrocarbyl group derived by incorporation of a compound selected from the group consisting of conjugated diene hydrocarbons, alkenylsubstituted aromatic hydrocarbons, and mixtures thereof; n is an integer from 0 to 5; Z is a branched or straight chain hydrocarbon group which contains 3-25 carbon atoms, optionally containing aryl or substituted aryl groups; J is oxygen, sulfur, or nitrogen; [A(R.sup.1 R.sup.2 R.sup.3)].sub.x is a protecting group, in which A is an element selected from Group IVa of the Periodic Table of Elements; R.sup.1, R.sup.2, and R.sup.3 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl groups containing lower alkyl, lower alkylthio, and lower dialkylamino groups, aryl or substituted…
