Conclusions
DSC thermoanalysis of polyblendsDSC thermoanalysis of polyblends- It was an exothermic reaction.- It could be further cross-linked with heating.
LW/EP polyblends (60/100) LW/EP polyblends (60/100) vs.vs.traditional eptraditional epoxy resinsoxy resins -heating with 90 for 3 h ℃-Its bonding strength was better.
