Method of preparing poly(arylene alkylenedicarboxylate)s of Formula (I) wherein Ar is an aromatic group, said group optionally incorporating one or two hydrocarbon chains to which the oxygen atoms are tethered; R 1 , R 2 , R 3 and R 4 are independently selected from hydrogen, alkyl, hydroxyl (OH), carbonyl (=0) and - O -acetyl (-0(C=0)CH 3 ), k is 0 or 1 and m is 0 or 1. and the use thereof. The present invention allows for utilization of biomonomers production of polyesters. |
