Effect of the solvent type and polymerization conditions on the curing kinetics, thermal and viscoelastic performance of poly(amide-imide) resins

open access: yeseXPRESS Polymer Letters, 2015
Isothermal and non-isothermal curing kinetics of both N-methyl-2-pyrrolidone (NMP) and N-methylimidazole (MI) based poly(amide-imide) (PAI) resins were investigated by DSC analysis using tightly closed high-pressure crucibles. Several exothermal peaks on
