The invention relates to a polymer comprising one or more diene units and bearing along the polymer backbone one or more pendant groups of the following formula (I): # imgabs0 # wherein: D represents a group attached to the polymer backbone; r1 represents a chemical group selected from the group consisting of-OCH3,-OCH2CH3 and-OR3; r2 represents a chemical group selected from the group consisting of-OCH3 and-OR3; with the proviso that R1 or R2 is-OR3; r3 represents a chemical group of formula (II): # imgabs 1 # wherein E represents a divalent C1-C12 hydrocarbon group optionally comprising one or more heteroatoms; x1, X2 and X3 may be the same or different and represent a hydrogen atom, a C1-C6 alkyl group or a C6-C14 aryl group; symbol * represents the connection of the chemical group of formula (II) to an oxygen atom. The invention also relates to a composition comprising at least one such polymer, a semi-finished product for a tyre or a tyre comprising at least one such polymer or one such composition.

    本发明涉及一种聚合物,其包含一个或多个二烯单元并且沿着聚合物主链带有一个或多个下式(I)的侧基,#imgabs0#其中:D表示连接至聚合物主链的基团;R1表示选自‑OCH3、‑OCH2CH3和‑OR3的化学基团;R2表示选自‑OCH3和‑OR3的化学基团;条件是R1或R2是‑OR3;R3表示式(II)的化学基团,#imgabs1#其中E表示任选地包含一个或多个杂原子的二价C1‑C12烃基;X1、X2、X3可以相同或不同,表示氢原子、C1‑C6烷基或C6‑C14芳基;符号*表示式(II)的化学基团与氧原子的连接。本发明还涉及包含至少一种此类聚合物的组合物、用于轮胎的半成品或者包含至少一种此类聚合物或一种此类组合物的轮胎。
