Study on synthesis of low viscosity polyamide

Yongli Peng

Abstract

Adipicacid,EDTA and triethylene tetramine were used as materials to prepare low viscosity Polyamide through melt polycondensation.Their structures were studied with FTIR,and the effect of reaction temperature,reaction time,the ratio of raw material on the product performance have been discussed and the best routing of epoxy resin curing agent was also studied.Test results indicated that when the molal weight ratio of adipicacid to EDTA was 1∶2.1,amidation reaction lasted for 2 hours under 180 ℃,and the curing agent had low viscosity and the best mixed mass ratio of curing agent to epoxy resin was 1∶5.
