Abstract
Copolyestercarbonates comprising carbonate structural units derived from at least one dihydroxyaromatic compound, preferably bisphenol A, and ester units derived from a dihydroxyaromatic compound and a composition comprising at least one C dimer acid may be prepared by an interfacial phosgenation method conducted at a pH in the range of about 9-11. The copolyestercarbonates have properties which are often superior to those of corresponding polymers prepared, for example, from dodecanedioic acid.
