BIODEGRADABLE THERMOPLASTIC POLYMER COMPOSTION, METHOD FOR ITS MANUFACTURE AND USE THEREOF

摘要

The object of the invention is a thermoplastic polymer composition susceptible to environmental degradation and/or organic recycling through composting, which is obtained entirely from compounds of natural origin, and a method for its manufacture. The composition according to the invention is obtained from polylactide (PLA) and from suitably modified thermoplastic starch (mTPS) obtained in the process of thermomechanical extrusion of a mixture of native starch (preferably potato and/or corn starch) with a suitable plasticizer (preferably glycerol), physical and mechanical, and chemical properties of which are additionally modified by compounds of natural origin, in the form of agar (AGR) and/or epoxidized vegetable oil (EOR), and/or by means of arabic gum (GA).
