BIODEGRADABLE MOLDING COMPOSITIONS INCLUDING AT LEAST ONE THERMOPLASTIC STARCH AND AT LEAST ONE THERMOPLASTIC ALIPHATIC POLYESTER.

摘要

The invention relates to biodegradable moulding compositions which are characterised in that they comprise from 5 to 60 % by weight of at least one thermoplastic aliphatic starch, from 30 to 94 % by weight of at least one thermoplastic polyester, preferably a polylactone, and from 1 to 10 % by weight of at least one salt of a hydroxycarboxylic acid. These compositions may be easily employed using conventional conversion processes such as extrusion.
