Abstract
A process for producing a modified polyaminoamide with markedly increased reactivity as an epoxy resin curing agent is disclosed. The process comprises introducing amino groups and mercapto groups into a polyaminoamide by using an aziridine compound and a thiirane compound. The modified polyaminoamide is capable of curing an epoxy resin at a low temperature and at a high rate to provide a cured epoxy resin excellent in anticorrosion and chemical resistance.
