PURPOSE: To obtain a reaction product of an ester which is excellent not only in oxidation resistance, hydrolysis resistance, etc., but also in compatibility with a hydrogen-containing fluoroalkane refrigerant and is suitable as a synthetic lubricant. ;CONSTITUTION: This reaction product of an ester...
Evidence is presented suggesting that alcoholysis and ester formation (Reactions 1 and 2), catalyzed by carboxylic acids, are important reactions of esters that could lead to larger molecules. Acidolysis (Reaction 3) proceeded at a comparatively slow rate and ester exchange reaction products (...
A process for poly(ester-carbonates) from dihydric phenols, especially bisphenol A; aromatic or cycloaliphatic dicarboxylic acids, especially terephthalic acid; and phosgene as carbonate precursor wherein a reaction of the acid and phosgene is carried out in a first stage forming dicarboxylic acid chl...
The present invention relates to resin compositions comprising a mixture of at least two resins, one resin consisting of the reaction product of an epoxidized fatty acid ester of a polyvalent alcohol with a carboxylic acid, and another resin consisting of a carboxylic acid-modified ester of a pol...
