본 발명은 사슬 말단에 화학식 I의 트리알킬실릴옥시 기를 갖는 말단 기-관능화 중합체에 관한 것이다. <화학식 I>상기 식에서, R, R및 R은 동일 또는 상이할 수 있고 알킬, 시클로알킬 및 아르알킬 잔기를 나타내고 이들은 O, N, S, Si와 같은 헤테로원자를 포함할 수 있다.
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.
