Patent ID: 7847048

Claim:
A polymer comprising (a) a repeat unit provided from a conjugated diene monomer and (b) a terminating group provided from a terminating compound of the formula: R 3 —(CH 2 ) x —Si(R 1 ) y R 2 3-y , where R 3 is R 1 can be the same or different and is an alkyl, a cycloalkyl, an allyl, and an aryl group with from about 1 to about 18 carbon atoms; R 2 can be the same or different and is —O (CH 2 ) p CH 3 or -(A(CH 2 ) n ) m ACH 3 where p is 0, 1, 2, or about 3, A is S or O, n is 1, 2, or about 3, and m is 1, 2, or about 3; x is an integer from about 1 to about 20; y is 0, 1, or 2; R 4 is an aryl or substituted aryl having from about 6 to about 18 carbon atoms, or a heterocycle or substituted heterocycle having from about 3 to about 18 carbon atoms; R 5 is hydrogen or a alkyl group having from about 1 to about 4 carbons; R 6 can be the same or different and is a hydrogen or an alkyl having from about 1 to about 4 carbons; wherein if (i) R 5 is H and (ii) R 4 is a phenyl or substituted phenyl, then R 2 is -(A(CH 2 ) n) m ACH 3 and m is 2 or about 3.
