    摘要: The esterification of neo acids catalyzed by the presence of a macro-reticular structured sulfonic acid cation exchange resin proceeds under mild conditions with a wide variety of alcohols to give readily recoverable esters in high yields and high purity and an easily recoverable and reusable catalyst.

    摘要: Soaps and ester-soaps of high molecular weight .alpha.-alkyl branched aliphatic monocarboxylic acids obtained from high molecular weight .alpha.-olefins are useful lubricants for structural resins. The high molecular weight acids useful for the preparation of the soaps and ester-soaps are obtained by the free radical addition of a short-chain monocarboxylic acid and .alpha.-olefins containing 22 or more carbon atoms. The soaps and ester-soaps of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.

    摘要: The present invention provides a process for obtaining mixed acid compositions having significantly increased polybasic acid contents from polymerized fatty acids. The improved polybasic acid compositions are obtained by heating a polymerized fatty acid containing 50 percent or more dimer acid in the presence of a free radical initiator. In addition to significantly increased polybasic acid contents the resulting products have essentially all the carboxyl functionality available as -COOH.
