ABSTRACT:
The present invention describes a method for the synthesis of saturated aliphatic polyesters by reaction of saturated or aromatic diacid chlorides with oligomeric aliphatic polyester diols, a method to thermally crosslink membranes prepared from the above saturated aliphatic polyesters, and the use of the crosslinked membranes to separate aromatics from saturates.
