POLYLACTAMIC/POLYOXYMETHYLENE BLOCK COPOLYMER

摘要

Block copolymer of the structure A-B, wherein- A polylactamic block of recurring units wherein PM is linear polymethylene chain having from 3 to 13 carbon atoms, - B is a polyoxymethylene block of recurring units ¢CH2O!. The block copolymer contains at least 2 wt.% of block B and at least 0.05 wt.% of block A. The block copolymer can be used as technopolymer when rich in block B, or in the field of yarns and molded products when ?ch in block A.
