본 발명은 사슬 말단에 화학식 I의 에테르-함유 메탄올 기를 갖는 말단-기 반응성 중합체에 관한 것이다. <화학식 I>상기 식에서, A는 C 및 H 이외에 O, N, S, Si와 같은 헤테로원자를 포함할 수 있는 2가 유기 기를 나타낸다. Polymer (I) having an ether containing carbinol group (II) at the end of the polymeric chain, is new. Polymer (I) having an ether containing carbinol group of formula (-O-A-OH) (II) at the end of the polymeric chain, is new.A = a divalent organic residue, in addition to C and H, further containing heteroatoms such as O, N, S or Si. Independent claims are included for: (1) for the preparation of (I); and (2) a vulcanizable rubber composition comprising (I) with end group (II) or a metal salt of formula ((-O-A-O ->) nM(n +>)) (III). M : a metal or semimetal with a valecny of 1-4, preferably Li, Na, K, Mg, Ca, Fe, Co, Ni, Al, Nd, Ti, Si or Sn; and n : 1-4.
