Abstract:
1. An end-modified diene copolymer wherein a living polymer of either a conjugated diene monomer alone or a mixture of the conjugated diene monomer and a vinyl aromatic monomer is modified with an organosiloxane compound represented by the following formula 1 and with an organosilane compound represented by the following formula 2: wherein R 1 and R 2 are the same or different and represent a hydrogen atom or a C 1 -C 20 alkyl group; X 1 , X 2 and X 3 are the same or different and represent a hydrogen atom, a C 1 -C 20 alkyl group, or a reactive group capable of reacting with the end of the living polymer, the reactive group being a halogen atom, a C 1 -C 20 alkoxy group, an epoxy group or an epoxy C 1 -C 20 alkyl group; at least one of X 1 , X 2 and X 3 is a reactive group; n is an integer between 1 and 1000; and m is an integer between 0 and 20; wherein Y 1 , Y 2 , Y 3 and Y 4 are the same or different and represent a C 1 -C 20 alkyl group, a C 1 -C 20 aminoalkyl group, NH 2 (CH 2 ) p —NH(CH 2 ) q — wherein p and q are each an integer between 1 and 20, a C 1 -C 20 alkylthio group, or a reactive group capable of reacting with the end of the living polymer, the reactive group being a chlorine atom, a C 2 -C 20 alkenyl group, a C 1 -C 20 alkoxy group, a C 1 -C 20 haloalkyl group, an epoxy group, an epoxy C 1 -C 20 alkyl group or an epoxy C 1 -C 20 alkoxy group.
