In the early stages of the introduction of the monoalkoxy titanates, hybrid titanates were introduced by the author, in which functions (3), (4), and (5) were intermixed by transesterification reactions at the Ti center of the molecules using various organic ligands. For example, the seventh in a series, titanate synthesized by the author was a hybrid titanate (KR 7) consisting of two moles of methacrylic acid and one mole of isostearic add (see Table 5.1). The theory, home out of commerdal practice, was that the isostearoyl ligand would stabilize and protect the methacrylic ligands from autooxidation.

In its simplest terms, the titanate function (1) mechanism may be classed as proton-reactive through solvolysis (monoalkoxy) or coordination (neoalkoxy) without the need of water of condensation, while the silane function (1) mechanism may be classed as hydroxyl-reactive through a silanol-sUoxane mechanism requiring water of condensation. The silane s silanol-siloxane water of condensation mechanism limits its reactions to temperatures below 100 °C, thereby reducing the possibility of in situ reaction in the thermoplastic or elastomer melt above 100 °C as is possible with titanates. In addition, a variety of particulate fillers such as carbonates, sulfates, nitrides, nitrates, carbon, boron and metal powders used in thermoplastics, thermosets, and cross-linked elastomers do not have surface silane-reactive hydroxyl groups, while almost all three-dimensional particulates and species have surface protons, thereby apparently making titanates universally more reactive. 

Titanate coupler n. One of a family of organo-titanium compounds first developed by Kenrich Petrochemicals in 1978 and burgeoning since then. Types available include monoalkoxy, chelate, coordinate, and quaternary salts. They form molecular bridges between organic matrices (resins) and inorganic fillers and reinforcements. Conductivities of metal-filled plastics are increased by one to four orders of magnitude, while melt viscosities are reduced by factors of 0.3-0.1.
