| abstract |
The present invention relates to cold flow reduced polymers with good processing behaviour, these having on the polymer chain end a silane-containing carboxy group of the formula (I), where R1, R2 are identical or different and are an H, alkyl, alkoxy, cycloalkyl, cycloalkoxy, aryl, aryloxy, alkaryl, alkaryloxy, aralkyl or aralkoxy radicals which can contain one or more heteroatoms, preferably O, N, S or Si, R3, R4 are identical or different and are an H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl radicals which can contain one or more heteroatoms, preferably O, N, S or Si, A is a divalent organic radical which, besides C and H, can contain one or more heteroatoms, preferably O, N, S or Si. |
