Enzymes which are capable of catalyzing esterifications and/or transesterifications such as selected lipases and esterases can, under specified conditions, convert certain lower linear oligomers of polyesters to their cyclic ester oligomers in quantities greater than would be predicted by thermodynamic calculation or prior art methods. The cyclic ester oligomers are useful for the production of higher molecular weight linear polyesters.

La présente invention concerne des enzymes capables d'effectuer des estérifications et/ou des transestérifications catalysantes de sorte que des lipases et des estérases sélectionnées puissent, dans des conditions spécifiées, transformer certains oligomères linéaires inférieurs de polyesters en leurs oligomères ester cycliques en quantités supérieures à celles qu'un calcul thermodynamique aurait prédit ou à celles obtenues dans les procédés de la technique antérieure. Ces oligomères ester cycliques conviennent pour la production de polyesters linéaires de masse moléculaire plus élevée.
