The depolymerization of polymers by enzymes is of great interest for biodegradable plastics, a group of materials which has been developed as an answer to increasing problems in plastics waste management. Polyesters play the dominant role in biodegradable polymers and recently a model of polyester degradation by hydrolyses (lipases) has been published. The chain mobility of the polymer chains p...
In this work we report on the processing, melt-drawing, and performance of new vanillic acid based aliphatic-aromatic thermotropic polyesters. It is demonstrated that these materials are easily processed from their nematic melts yielding highly oriented products. Furthermore, we demonstrate that a molecular weight (Mw) of roughly 30 kg/mol is required in order to successfully perform spinning o...
In a previous article,1 the development and molecular characterization of three polyesters from Ncarbobenzyloxy-L-glutamic acid (ZGluOH) were reported. The polymers were a linear, heterochain polyester (ZGluOH and ethylene glycol), a crosslinked heterochain polyester (ZGluOH and diglycidyl ether of 1,4-butanediol), and a crosslinked, heterochain aromatic polyester (ZGluOH and diglycidyl ether o...
