<p>A composition comprising a comminuted inorganic material and an organotitanate compound or a reaction product thereof, the organotitanate compound being present in an amount of at least 0.01 parts by weight per 100 parts by weight of inorganic material and having one of the following formulae: (I) (RO)zTi(A)x(B)y (II) (RO)Ti(OCOR')p(OAr)q (III) (RO)Ti(OCOR"")3 wherein R is a substituted or unsubstituted monovalent alkyl, alkenyl, alkynyl, or aralkyl group; A is substituted or unsubstituted thiophenoxy, thionaphthyloxy, sulfonic, diester pyrophosphate or diester phosphate; B is OCOR' or aroxy, wherein R' is hydrogen or is a substituted or unsubstituted alkyl, alkenyl, aryl, aralkyl or alkaryl group; OAr is phenoxy or naphthyloxy; R"" has the definition of R, except that the total number of carbon atoms in the three R"" groups in a molecule is not more than 14; x + y + z equals 4, p + q equals 3, each of x, z and q is 1, 2 or 3, and y and p are 0, 1 or 2. The foregoing compositions are useful as fillers, pigments, reinforcements and chemical reactants in polymers. Another aspect of the invention is a polymer composition comprising a polymeric material in admixture with a titanate as defined above and comminuted inorganic material, or a reaction product of said titanate and said inorganic material.</p> |
