Abstract

Polyamides are prepared by condensing an alkylene diamine H2N(CH2)xNH2 where x = 4 to 20 with a polymeric fat acid, or a functional derivative thereof, having a dimer content >90% by weight; the molar equivalent of amine is substantially equal to the molar equivalent of carboxyl groups employed. Examples of suitable diamines are 1,6-diaminohexane, 1,4-diaminobutane, 1,8-diamino-octane, 1,9-diaminononane, 1,10 - diaminodecane and 1,12 - diaminododecane. The polymeric fat acid may be derived by polymerization from saturated or unsaturated long-chain C8-C24 aliphatic acid. A polymeric mixture of oleic and linoleic acids derived from tall oil fatty acids is particularly suitable. Condensation may be effected at 150-300 DEG C. for 30 minutes to 8 hours.
