| abstract |
The present invention relates to end-group-functionalized polymers, which at the polymer chain end a silane-containing carboxy group of the formula (I) have, wherein R 1 , R 2 are the same or different and represent H, alkyl, alkoxy, cycloalkyl, cycloalkoxy, aryl, aryloxy, alkaryl, alkaryloxy, aralkyl and aralkoxy radicals which contain one or more heteroatoms, preferably O, N, S or Si, R 3 , R 4 are the same or different and represent H, alkyl, cycloalkyl, aryl, alkaryl and aralkyl radicals which may contain one or more heteroatoms, preferably O, N, S or Si, A is a divalent organic radical which, in addition to C and H, may contain one or more heteroatoms, preferably O, N, S or Si. |
