ABSTRACT:
The invention relates to an alloy composition possessing improved properties of mechanical resistance. The composition contains a starch, which is preferably plasticised, and a polymer which acts as coupling agent which is chosen from the group consisting of polyolefins modified by chemical functional groups which are active towards the hydroxyl functional groups of starch.
Generally, the composition also contains a thermoplastic polymer.
The invention also relates to the process for preparing this composition and the use of these compositions for the manufacture of films intended for the paper market and for packages made from biodegradable plastic.
