Biodegradable polymer blend

摘要

A biodegradable polymeric blend is provided, which can be produced by extrusion and contains at least one partly aromatic polyester, as well as aromatic and aliphatic blocks. At least 10% w. of this polymeric blend with the partly aromatic polyester contains one aliphatic polyester based on at least one hydroxycarboxylic acid and/or at least one lactone, the glass transition temperature (TG) of the aliphatic polyester being of at least 50°. This polymeric blend advantageously includes no plastifying agent and, moreover, comprises regenerating materials.
