Long-life bio-based plastics, method for producing same and usage thereof

Bio-based plastic comprises at least one polyester resin and/or a mixture of at least one aromatic monomeric carbodiimide and at least an aromatic oligomeric and/or aromatic polymeric carbodiimide, where the ratio of aromatic monomeric to aromatic polymeric and/or aromatic oligomeric carbodiimide is greater than 1:1. An independent claim is also included for preparing the bio-based plastic, comprising mixing at least a polyester resin with at least one aromatic monomeric carbodiimide and at least one aromatic oligomeric and/or aromatic polymeric carbodiimide in a mixing unit, where the ratio of aromatic monomeric to aromatic polymeric and/or aromatic oligomeric carbodiimide is greater than 1:1. Gegenstand der vorliegenden Erfindung sind neuartige langlebige und hydrolysestabile biobasierte Kunststoffe auf Basis von Polyesterharzen, ein Verfahren zu deren Herstellung und deren Verwendung.
