摘要: There is provided a co-condensation product obtainable by subjecting a p-alkylphenol to reaction with formaldehyde in the presence of an alkali catalyst to prepare a resol type condensate, and subjecting the resulting resol type condensate to reaction with a m-substituted phenol such as resorcin in the presence of an acid catalyst, wherein the content of the m-substituted phenol is not higher than 4% by weight, and the content of a component having a molecular weight not higher than 1,000 excluding both the p-alkylphenol and the m-substituted phenol is at least 25% by weight based on the total weight of the co-condensation product. This co-condensation product is low in fuming and in hygroscopic properties, exhibits excellent adhesiveness in vulcanizing adhesion between rubber and a reinforcing material, and further provides a vulcanized rubber article of high hardness.

摘要: A bisphenol monoester represented by the formula (I) :
wherein R 1 is hydrogen or alkyl, R 2 and R 3 are each alkyl, and R 4 is alkyl, alkenyl or phenyl, is produced by continuous two step reactions in which an aldehyde R 1 -CHO and 2,4-dialkylphenol are subjected to a condensation reaction in a C 6 -C 10 aliphatic or C 6 -C 12 aromatic hydrocarbon solvent, and then a resulting bisphenol compound dissolved in the solvent is subjected to an esterification with a carboxylic acid R 4- COOH or its derivative. Prior to the esterification, the organic layer containing the bisphenol compound is subjected to a dehydration treatment, thereby enabling the two steps to proceed continuously without isolating the intermediate bisphenol compound. A purification process for the bisphenol monoester of the formula (I) is also disclosed in which the monoester is purified from a mixed solvent comprising a C 6 -C 12 aromatic hydrocarbon solvent and a C 1 -C S alcohol or C 2 -C 3 aliphatic nitrile solvent.-
