摘要:
A block copolymer is produced fromI. 1 to 60% by weight of at least one telechelic diene polymer containing terminal carbonate ester, --OH--, --NH.sub.2 --, carboxylic acid or carboxylic acid ester groups and having a molecular weight M.sub.n of from about 400 to 1300, andII. 99 to 40% by weight of at least one polyamide or polyamide-forming component.
