<P>PROBLEM TO BE SOLVED: To provide a terminal-modified conjugated diene-vinyl aromatic copolymer and a method for manufacturing the same. <P>SOLUTION: The terminal-modified conjugated diene-vinyl aromatic copolymer is obtained by reacting a conjugated diene-vinyl aromatic copolymer with active terminal with polysiloxane. The polysiloxane is expressed by chemical formula (I), wherein R1, R2, R3 and R5 independently are alkyl group with 1-20 carbon atoms, R4 is selected from one of alkyl group, alkoxy group or hydroxyl group with 1-5 carbon atoms, m is an integer of 2-50, and n is an integer of 0-50. <P>COPYRIGHT: (C)2012,JPO&INPIT |
