nylonzusammensetzung with increased hydrolysierbarkeit and procedures to increase the hydrolysierbarkeit of nylon

摘要

The present invention provides a nylon composition having increased hydrolyzability which is obtained by physically mixing 100 parts by weight of a nylon with 1 to 50 parts by weight of at least one of polylactic acid, polyglycolic acid and a copolymer containing 50 mol% or more of a lactic acid unit or a glycolic acid unit as a repeating unit in its chain; and a method for increasing the hydrolyzability of a nylon by preparing such a composition. According to the present invention, the high hydrolyzability can be imparted to the nylon inherently having extremely low hydrolyzability without impairing its original mechanical strength. Therefore, various molded articles made from the nylon can be hydrolyzed under natural circumstances, and thus the wastes are not stored.
