PURPOSE:To provide a composition imparted in the high hydrolyzability without deteriorating the original characteristics of nylon and not accumulated as industrial wastes, by adding polylactic acid, polyglycolic acid, etc., to nylon. CONSTITUTION:100 pts.wt. of a nylon is physically mixed with 1-50 pts.wt. of at least a polymer selected from a group consisting of polylactic acid, polyglycolic acid and a copolymer containing >=50mol.% of lactic acid units or glycolic acid units as repeating units in the copolymer chain. The copolymer includes a lactic acid-glycolic acid copolymer. |
