| titleOfInvention | Improvements in or relating to polyamide resins |
| abstract | A polyamide resin comprises the reaction product of (a) a polymeric fatty acid, (b) a dibasic acid containing from 5 to 10 carbon atoms, (c) an alkylene diamine containing from 2 to 6 carbon atoms and (d) a polyalkylene polyamine containing from 3 to 5 amino groups and in which the alkylene groups contain from 2 to 3 carbon atoms. Specified polymeric fatty acids are those derived from the polymerization of drying or semi-drying oils or from the polymerization of the free acids or simple aliphatic alcohol esters of the acids of soyabean, linseed, tung, perilla, corn, oiticica, cottonseed, tall, sunflower, safflower or dehydrated castor oils. Specified dibasic acids are glutaric, adipic, pimelic, suberic, azelaic, sebacic, terephthalic and isophthalic acids. Alkylene diamines specified are ethylene and hexamethylene diamine, 1 : 3-diamino propane, 1 : 3-diamino butane, 1 : 4-diamino butane and 3-(isopropylamino-)-propylamine. Polyalkylene polyamines specified are diethylene triamine, trimethylene tetramine, tetraethylene pentamine and 3 : 31-imino-bis-propylamine. The examples describe the preparation of resins from ethylene diamine, unsaturated fatty acid monomer, polymerized fatty acid, sebacic acid and diethylene triamine, the products being soluble in a phenol-butanol mixture. |
