A BIO-BASED POLYMER ADDITIVE, A PROCESS FOR PREPARING THE BIO-BASED POLYMER ADDITIVE AND A BIODEGRADABLE POLYMER COMPOSITION COMPRISING SAID BIO-BASED POLYMER ADDITIVE

摘要

The present invention bio-based polymers additives, their preparation and manufacture of biodegradable plastics a biodegradable polymer composition containing the additive for use in a bio-based polymer is disclosed. The additive is prepared from algae, yeast or comminuted biomass of microbial cells, such as another micro-organism. In particular, the bio-based polymer additives to improve the flow properties and / or biodegradability of the polymer. In particular, the additive is used as a pigment. ;
