    摘要: Polyester and polyester carbonates corresponding to the following formula ##STR1## in which R.sup.1 to R.sup.4, o to r, n, a and b and also X.sup.1 and Y.sup.1 are as defined in the specification,may be obtained by interfacial condensation from bisphenols corresponding to the following formula. ##STR2## aromatic dicarboxylic acid chlorides corresponding to the following formula ##STR3## and phosgene. The new polyesters and polyester carbonates combine outstanding heat resistance and light stability. They may be used both as thermoplastic materials as such or as constituents of polymer blends or even as UV (light) stabilizers or as UV (light)-stabilizing coatings. Accordingly, they have degrees of polycondensation n in the range from 2 to 100.
