Abstract of Disclosure A composition of matter which consists of a filled polyester compositions containing specific organo-titanate salts. These salts may be represented by the following formulas: (I) (RO)zTi(A)x(B)y and (II) (RO)Ti(OAr)p(OCOR')q where R is a monovalent alkyl, alkenyl, alkynyl or aralkyl group having from 1 to about 30 carbon atoms or a substituted derivative thereof; A is a monovalent thioaryloxy, sulfonyl, sulfinyl, diester pyrophosphate, diester phosphate or a substituted derivative thereof; B is OAr or OCOR'; R' is hydrogen or a monovalent organic group having 1 to about 100 carbon atoms; OAr is aryloxy; the sum of x, y and z equals 4; x and z may be 1, 2 or 3; y may be 0, 1 or 2; and p+q equals 3. Among the advantages of the invention are improved flex modulus, flexural strength, impact strength, better mold flow and higher gloss to molded products. The physical property improvements are maintained after aging even in the presence of steam or boiling water.
