Abstract:
A polymer of the formula whereineach FG is independently hydrogen, a protected functional group, a non-protected functional group, the residue of a difunctional coupling agent, or the residue of a multifunctional coupling agent, with the proviso that when each T is oxygen, then FG is not hydrogen; each Q is independently a saturated or unsaturated hydrocarbyl group derived by incorporation of one or more conjugated diene hydrocarbons, one or more alkenylsubstituted aromatic compounds, or mixtures of one or more conjugated diene hydrocarbons with one or more alkenylsubstituted aromatic compounds; each x is independently the number of units of conjugated diene hydrocarbons, alkenylsubstituted aromatic compounds, or mixture thereof and ranges from about 10 to about 2000; each Z is independently a branched or straight chain hydrocarbon connecting group which contains 3-25 carbon atoms, optionally substituted with aryl or substituted aryl; each T is independently selected from the group consisting of oxygen, sulfur, nitrogen, and mixtures thereof; (Aâ€”R1R2R3) is a protecting group, in which each A is independently an element selected from Group IVa of the Periodic Table of the Elements; and R1, R2, and R3 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl, and substituted cycloalkyl; R, R4, and R5 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl and substituted cycloalkyl; h is 0 when T is oxygen or sulfur, and 1 when T is nitrogen; l is an integer from 1 to 7; m is 1 when T is oxygen or sulfur, and 2 when T is nitrogen; n is 2 or 3; w is 0 or 1; and y is 1.
