Abstract: Sulfuric acid compounds are removed from reaction mixtures by a reaction with polybutadiene alone or combined with unsaturated terpene compounds at elevated temperatures whereby products of reduction are formed which are volatilizable at the temperature of reaction and by expelling said products of reduction from the reaction mixture. Thus a product being substantially free from a sulfur content is obtained.

Abstract: A process for the preparation of a flexible phenolic resin which comprises co-condensing a dimethylol phenol, substituted by an alkyl group having from 1 to 20 carbon atoms, with a methylol derivative of a polyfunctional phenol in which derivative at least half of the reactive hydrogen atoms in the polyfunctional phenol are substituted by methylol groups and wherein the ratio of the methylol groups of the derivative of the polyfunctional phenol per mol of the dimethylolalkyl phenol is from 1.4:1 to 6:1, a phenolic resin prepared by said process, a coating composition containing said phenolic resin and an article coated with or comprising said phenolic resin.

Abstract: A process for preparing modified copolymers while substantially reducing disintegration, which copolymers contain carboxylic groups to which cations of polyvalent metals are bound which comprises reacting in a first stage a solution of a copolymer containing anhydride groups of vicinal carboxylic groups or a combination of such anhydride with vicinal carboxylic groups and/or other radicals capable of forming vicinal carboxylic groups with certain alcohols to yield a reaction product in which at least a part of the anhydride groups is converted to semiester groups, and reacting the product thus obtained in the presence of water at a temperature in the range from 50.degree. to 120.degree. C with a salt-forming compound of a polyvalent metal. The invention is also directed to resinous compositions, particularly printing inks, containing such products.
