Patent ID: 6861482

Claim:
A resorcinol ester polycarbonate polymer having good flow characteristics comprising: (a) a resorcinol arylate polyester chain, wherein the resorcinol arylate polyester chain is substantially free of anhydride linkages such that the resorcinol arylate polyester chain comprises the condensation of at least one resorcinol moiety with at least one dicarboxylic acid dichloride while maintaining the pH between about 3 and 8.5 through the presence of an acid acceptor, wherein the total molar amount of acid chloride groups is stoichiometrically deficient relative to the total molar amount of phenolic groups on the resorcinol moiety; (b) at least one organic carbonate group; and (c) at least one soft-block chemical moiety, wherein the at least one soft-block chemical moiety is added in an amount to provide a reduction in melt viscosity and flow energy for the polymer.
