Abstract
Abstract A multiply-branched aliphatic-aromatic polyester and a method for producing that polymer. The method comprises condensing Z 1 and Z 2 groups of a branching reactant having the general formula Z 1 --Ar--(Z 2 )j. In this formula, j is 2 or 3 and Ar is an aryl or heteroaryl group having from 1 to 3, solitary or linked or fused, substituted or unsubstituted, five or six membered rings. One of Z 1 and Z 2 is a group having the ##STR1## general formula in which R 1 is selected from the group consisting of hydroxy, chloro, bromo, monovalent alkoxide having from 1 to about 6 carbons, and --O--(CH 2 ) d --OH, wherein d is an integer from 1 to 3; and the other is a group having the general formula ##STR2## in which R 2 is a divalent alkyl group having from 1 to about 6 carbon atoms, and g is an integer from 0 to about 100.
