Abstract
A modified diene polymer is provided which may be added to a rubber composition together with a filler to allow the filler to be dispersed in a crosslinked product of the composition in a state that is ideal for attaining enhanced properties. A method for producing such modified diene polymers is also provided. The modified linear diene polymer has a specific functional group only at one end thereof, the average number of the functional groups per molecule being 0.8 to 1.
Claims6
A modified linear diene polymer having a functional group of the following formula (1) only at one end thereof, the average number of the functional groups per molecule being 0.8 to 1,
- wherein R1, R2 and R3 are each independently a methoxy group, an ethoxy group, a phenoxy group, a methyl group, an ethyl group or a phenyl group, at least one of R1, R2 and R3 is a methoxy group, an ethoxy group or a phenoxy group, and X is a divalent alkylene group having 1 to 6 carbon atoms.
