End group functionalized polymer exhibiting a trialkylsilyloxy group (I) at its chain end, is new. End group functionalized polymer exhibiting a trialkylsilyloxy group of formula (-(O-Si(R1)(R3)-R2)) (I) at its chain end, is new. R1-R3 : alkyl, cycloalkyl or aralkyl (contains O, N, S or Si). Independent claims are also included for: (1) preparing the end groups functionalized polymer; (2) a vulcanizable rubber composition comprising antioxidants, oils, fillers, rubber and/or rubber auxiliaries, and the end group functionalized polymer having end groups (I) or hydroxyl end groups produced from (I); (3) tires obtainable from the vulcanizable rubber composition; and (4) moldings obtainable from the vulcanizable rubber composition. |
