Polylactic composition, useful e.g. to make molded-, extruded- and thermoformed articles, comprises polylactic acid, ethylene copolymer e.g. ethylene-methylacrylate-glycidyl methacrylate and ethylene-alkyl(meth)acrylate copolymer |
摘要 |
Polylactic composition comprises polylactic acid (PLA) at 60-97 wt.% and a polymer mixture at 3-40 wt.%. The polymer mixtures comprises a copolymer (I) of ethylene and an unsaturated monomer with epoxy, carboxylic acid or its anhydride units and optionally alkyl(meth)acrylate, and an ethylene-alkyl(meth)acrylate copolymer (II). The weight ratio of (I) to the sum of (I) and (II) is 0.1:0.49. Independent claims are included for: (1) a process of preparing the composition comprising extruding the PLA with the polymer mixture; (2) a part/article obtained by molding, extruding and thermoforming the composition; and (3) a multi-layer structure comprising a layer made up of the composition, and at least a layer made up of thermoplastic e.g. polyethylene, polypropylene, polystyrene, polyamide or and ethylenevinyl alcohol copolymer. |
