| abstract |
The present invention relates to diene polymers having, at the beginning of the polymer chain, tertiary amine groups of formulas (I) or (II), (see Formulas) in which R1, R2 are the same or different and represent each alkyl, cycloalkyl, aryl, alkaryl and aralkyl groups which may contain heteroatoms such as O, N, S and / or Si; Z represents a divalent organic group that, in addition to C and H, may also contain heteroatoms such as O, N, S and / or Si; and, at the ends of the polymer chains, carbinol groups containing silane of formula (III) (see Formula) or their metal salts or their semimetal salts, wherein R3, R4, R5, R6 are the same or different and each represents H or alkyl, cycloalkyl, aryl, alkaryl and aralkyl groups which may contain heteroatoms such as O, N, S and / or Si; A is a divalent organic group that, in addition to C and H, may also contain heteroatoms such as O, N, S and / or Si. |
