Abstract: New chelate compounds which are alpha,omega-alkylene titanates having two non-hydrolyzable groups. The compounds may be represented by the formula: ##STR1## where A represents a non-hydrolyzable group, B is an R.sub.2 C group or a carbonyl group, R may be hydrogen or alkyl groups having 1 to 6 carbon atoms and n may be 1 or 2. Preferably R is hydrogen. The R in a particular molecule may be the same or different.The compounds are particularly useful for treating inorganic fillers which are used to extend or modify the properties of polymeric materials. The compounds maintain high activity even when applied to filler containing free water.

Abstract: This invention relates to adducts of tetra-substituted titanates and di-substituted hydrogen phosphites; the use of such adducts for treating particular fillers, including pigments; the compositions of fillers and the aforesaid adducts with epoxy resins and other casting resins; the reaction product of said adducts with aromatic polyamines; the use of said reaction products for curing epoxide and urethane resins; and compositions of certain of the adducts and casting resins. The titanate-phosphite adducts serve to reduce the viscosity of filled epoxy resins, thereby permitting higher filler loading, to enhance the tinctorial power of pigments, and to render casting resins water-extendible. The titanate-phosphite adducts are the reaction products of one mole of a compound having the formula (RO).sub.4 Ti and two moles of di-substituted hydrogen phosphite, (R'O).sub.2 P(O)H, where R and R' are monovalent alkyl, alkenyl, aryl, aralkyl or alkaryl.

Abstract: This invention relates to the use of certain organo-titanium salts for use with fillers for the preparation of epoxy resins and other liquid thermosetting resins; the resulting filled resin compositions; and compositions of such salts and such liquid resins.The organo-titanate salts of the invention may be represented by the formulas:(RO).sub.z Ti(A).sub.x (OAr).sub.y, (I)roti(OAr).sub.3 (II)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; OAr is aroxy or a substituted derivative thereof; the sum of x, y and z equals 4; x and z may be 1, 2 or 3; and y may be 0, 1 or 2; or ##STR1## where A' represents a non-hydrolyzable group as defined above for A or an aryl group, B is an alkylene group (CR.sub.
