| 摘要 |
The invention relates to a process for producing a shaped article having improved optical properties compared to a polyamide 12/polytetramethylene block copolymer. The article is made from a block copolymer PAX.Y/PE where polyamide (PA) blocks are selected from PA 10,12; PA 6,18; PA 10,14; and PA 12.12; alternating with polyether (PP blocks, selected front the group consisting of: PE blocks comprising hydroxyl ends, and PE blocks comprising NH2 ends; wherein said PE blocks comprise from 0 to 39% by weight of polytrimethylene ether glycol PO3G and/or polyethylene glycol PEG and from 100 to 61% by weight of polyether other than PO3G or PEG. The formed article is a fabric, film, sheet, rod, pipe, injection-molded component, or a shoe sole.
