摘要：A block copolymer of 99.8 to 90 % by weight of a polyamide segment and 0.2to 10 % by weight of a polyether segment dispersed in an island state of not more thanabout 10 &mgr; in particle size, the polyamide segment comprising at least one diaminecomponent containing 100 to 50 mol % (preferably 100 to 70 mol %) of m-xylylenediamine or its mixture with p- xylylenediamine and at least one dicarboxylic acidcomponent containing 100 to 50 mol % (preferably 100 to 70 mol %) of at least onealiphatic dicarboxylic acid having 6 to 12 carbon atoms, the polyether segmentcomprising at least one polyether having a molecular weight of 2,000 to 20,000 and anamino group or a carboxyl group at at least one terminal position thereof and the blockcopolymer having a scattering index of not less than 1.
