    Abstract: This invention provides a process for producing an aqueous resin dispersion in which the average particle diameter of the dispersed resin is not more than 500 nm, comprising finely dispersing a monomeric mixture (I) containing (A) fatty acid-modified polymerizable unsaturated monomer and (B) other polymerizable unsaturated monomer which is copolymerizable with the monomer (A) in an aqueous medium in such a manner that the dispersed particles have an average particle diameter not more than 500 nm, and polymerizing the resulting emulsified product. The invention also provides aqueous resin compositions which comprise the aqueous resin dispersions, and water-based paint compositions which comprise the aqueous resin compositions.

    Abstract: The present invention is directed toward anionic polymerization employing lithio amines mixed with an organic alkali metal compound and optionally, a chelating reagent. The lithio amines have the general formula (A)Li(SOL)y, where SOL is a solubilizing component, A is an alkyl, dialkyl, cycloalkyl or dicycloalkyl amine radical or a cyclic amine, and y is 0 or is from about 0.5 to about 3. The invention is also directed toward polymers and other products made using the initiator, and methods therefor. Further, the invention contemplates a polymer, a polymer composition and products therefrom, which include a functional group from the reaction product of an amine and an organolithium compound. The resulting polymers may be terminated with a terminating, coupling or linking agent, which may provide the polymer with a multifunctionality.

    Abstract: A process for crystallizing the adduct of bisphenol A with phenol from a phenol solution in the presence of water comprises controlling the concentration of bisphenol A in said solution by removing portion of the phenol from said solution or adding phenol to said solution according to feedback control based on the measurement of solution density to obtain an adjusted solution, and feeding the adjusted solution to the crystallizer in which its inside wall is kept at a temperature higher than that of the adjusted solution, provided the temperature difference being smaller than 5.degree. C. The crystallized adduct has a uniform particle size and a high purity.

    Abstract: This invention is a process for the preparation of bisphenol A from acetone and phenol. By this invention, the formation of by-products is extremely decreased and post treatment steps can be simplified.This invention involves the following steps. (1) One mole of acetone is reacted with 4 to 12 moles of phenol in the presence of a sulfonic acid type cation exchange resin catalyst modified with a mercapto group-containing compound such as mercaptoethylamine to convert 20 to 60% of acetone, and (2) the reaction mixture containing unreacted acetone is successively reacted to the presence of the hydrochloric acid catalyst.The formation of by-products such as 2-(2-hydroxyphenyl)-2-(4-hydroxyphenyl)propane, Dianin's compound and the like is remarkably reduced by the process of this invention.
