Abstract: The invention relates to epoxy resins admixed with cumylphenol or the carboxylic acid ester or the glycidyl ether thereof. The cumylphenol or its derivative serves as an accelerator for amine-cured epoxy systems, as a reactive diluent copolymerizable with epoxy resins, or as a non-reactive plasticizer.

Abstract: Novel organo-titanates, mixtures thereof, and products thereof and inorganic particulate surfaces and methods of making such reaction products. The reaction, which preferably occurs in an organic medium, modifies the inorganic surface by forming a monomolecular organic complex layer. The modified surface causes complete dispersion and improved compatibility of the inorganic particles or fibers in organic media and results in lower viscosity, high inorganic-to-organic ratios than heretofore obtainable, and improved physical properties in polymer systems, and more complete chemical utilization of reactive inorganic compounds.

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.
