Abstract
Compositions comprising copolyetherester resins, copolyetherimide ester resins, or mixtures thereof, in combination with a high molecular weight polyester resin or mixture of such resins, 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 properties suitable to replace ceramics and filled thermosets in many important applications.
