ABSTRACT:
Aliphatic polyesters are produced by the acylative ether cleavage of aliphatic monomers having at least one arylmethoxy group and at least one hydrocarbyl group. Alternatively, monomeric systems of aliphatic compounds having at least two arylmethoxy groups together with aromatic or aliphatic compounds having at least two halocarbonyl groups are used. Lewis acids are used to catalyze the reaction.
