(8CV-5261) ABSTRACT OF THE DISCLOSURE Compositions comprising a high molecular weight polyester resin derived from a cyclohexanedimethanol and a hexacarbocyclic dicarboxylic acid or mixture of such resins and, optionally, a second linear high molecular weight polyester, optionally further combined with an effective, impact strength-improving amount of a thermoplastic elastomer, such as a polyether ester or a polyetherimide ester, with relatively high loadings of fillers selected from zinc oxide, barium sulfate, zirconium oxide, zirconium silicate, strontium sulfate or a mixture of any of such fillers, provide highly dense thermoplastic molded articles with improved impact strength and properties suitable to replace ceramics and filled thermosets in many important applications.
