Abstract
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.
