Abstract

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.
