    摘要: The invention relates to novel polyamides substantially based on polycarboxylic acids, in particular polymerized fatty acids, and polyalkylene polyamines in which the recurring alkylene groups are of different carbon chain lengths and two or more different alkylene imine groups occur. These polyamides show amine values from 5-600, acid values below 2 and viscosities of 0.05-25 Pa s and are useful as curing catalysts for epoxy resins.

    摘要: High molecular weight carboxylic acids are provided. The mixed acid products of this invention typically contain a high percentage of aliphatic straight-chain monocarboxylic acids containing 22 or more carbon atoms. The monocarboxylic acids are obtained by the ozonization of high molecular weight .alpha.-olefins under controlled conditions. Using this ozonization process it is possible to obtain mixed acid products wherein the predominant acids contain 22 to 35 carbon atoms. An additional feature of this invention is the ability to obtain mixed acid products wherein acids having an odd number of carbon atoms are present in significantly larger amounts than acids having an even number of carbon atoms.

    摘要: Soaps and ester-soaps of high molecular weight branched- and straight-chain aliphatic monocarboxyic acids obtained from .alpha.-olefins containing 22 or more carbon atoms are useful lubricants for structural resins. 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 to C.sub.22.sub.+ olefin or by ozonization of the C.sub.22.sub.+ olefin. The products of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.
