ABSTRACT:
Polyamides containing free amino groups and suitable for use as curing agents for polyepoxy compounds are derived from (a) a polybasic acid component comprising polymeric fatty acid together with from 10 to 90 mole %, based on the total acid component, of one or more aromatic dicarboxylic acids containing two carboxylic acid groups and one benzene ring, each carboxylic acid group being directly linked to a benzene ring, and (b) a polyamine component containing at least 50 mole % of one or more aliphatic polyamines containing at least three amino groups per molecule.
Cured resinous composition may be prepared by reacting the polyamides with polyepoxy compounds and curable composition contain the polyamides together with polyepoxy compounds.
