Abstract

Novel metaled fatty polyesters were prepared using polytransesterification reactions between dimethyl terephthalate (DMT) and different fatty metaled (Si/Ge) alcohol obtained from the undec-10-en-1-ol. The corresponding yields were excellent and the structure of the polyesters were determined by spectroscopic methods. Considering one hour of polymerization, the polymers exhibited acceptable molecular weights. The thermogravimetric analysis showed that these polyesters were more stable than their corresponding monomers and presented thermal degradation above 400°C.
