Polymer composition based on poly lactic acid, useful in piece/object, comprises poly lactic acid and additive mixture, for promoting crystallization of poly lactic acid, comprising mineral filler, glycol polyether, and aliphatic amide

摘要

Polymer composition based on poly lactic acid comprises poly lactic acid and a mixture of additives promoting the crystallization of poly lactic acid, where the mixture of additive comprises a mineral filler, a glycol polyether, and an aliphatic amide. Independent claims are included for: (1) a preparation of the polymer composition comprising mixing the poly lactic acid and the additives; and (2) a piece or object obtained from the composition where the piece or object is obtained by casting, extrusion or thermoforming.
