Abstract
All-aromatic hyperbranched polysters with phenol and acetate and groups were prepared by the melt condensation of the A 2 B monomers 3,5-bis(trimethylsiloxy)benzoyl chloride (2) and 3,6-diacetoxybenzoic acid (3). The trimethylsilyl groups of the polyesters from monomer 2 are hydrolyzed during workup, resulting in polymers with phenol terminal groups. Although the acetate groups of polymers prepared from 3 are quite stable and remain in the polymer, conditions were found where they could be hydrolyzed to give a phenolic polymer similar to that obtained from 2
