摘要 |
A functionalized elastomer comprising the reaction product of (1) a living anionic elastomeric polymer comprising units derived from divinylbenzene and a monomer comprising isoprene; and (2) a polymerization terminator of formula:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ Q-(CH 2 ) X Si(OR 1 ) Y R 2 3-Y ,
is disclosed. Q is R 3 CH=N- or (R 4 ) 2 N-. R 3 represents a group consisting of an aryl or substituted aryl having from 6 to 18 carbon atoms, or a heterocycle or heteroaryl having from 3 to 18 carbon atoms. R 4 independently represents an alkyl group having from 1 to 6 carbon atoms. R 1 and R 2 each independently represents a group having from 1 to 18 carbon atoms selected from the group consisting of an alkyl, a cycloalkyl, an allyl, and an aryl. X is an integer from 1 to 20. Y is an integer from 1 to 3. Units derived from the terminator are exclusively disposed adjacent to units derived from the divinylbenzene. |
