Curing of Epoxy Resin with Styrene–Maleic Anhydride Copolymer: A Differential Scanning Calorimetric Investigation

Curing reactions of epoxy resin (EP-450) with stryene–maleic anhydride copolymer (St–MAn) samples are investigated by differential scanning calorimetry at a scan rate of 10 °C min −1 in an N 2 atmosphere. The overall kinetic parameters of the curing reactions are estimated using Barrett as well as F...

Description
Summary:Curing reactions of epoxy resin (EP-450) with stryene–maleic anhydride copolymer (St–MAn) samples are investigated by differential scanning calorimetry at a scan rate of 10 °C min −1 in an N 2 atmosphere. The overall kinetic parameters of the curing reactions are estimated using Barrett as well as Freeman–Carroll methods based on a single dynamic scan. The curing reactions are found to follow overall first-order kinetics up to about 60–70% completion. Thermogravimetric analysis (TGA) of all the cured samples of epoxy resin (EP-450) with St–MAn copolymer samples has also been carried out at a heating rate of 10 °C min −1 in air.
