Claims14
A polyester molding composition comprising a cycloaliphatic polyester resin and a nucleating agent comprising a fluoropolymer containing a second thermoplastic resin, wherein the nucleating agent is a free-flowing powder with a particle size in the range of 20 to about 1000 microns and the cycloaliphatic polyester resin comprises residues of a cyclic aliphatic diol and residues of a cyclic aliphatic diacid, wherein at least 50% mole of the residues are residues of cyclic diols and diacids and the remainder, if any, are residues of linear aliphatic diacids or diols.
