Curing behaviors and thermal degradation kinetics of polybenzoxazine-polycaprolactone blends

Abstract

In this study, the blends of polybenzoxazine (PBA-a)/polycaprolactone (PCL) was prepared at the weight ratio of 100/0, 80/20, 60/40, 40/60, 20/80, and 0/100. The curing behaviors of the blends were studied. The results reveal that the curing temperature of the blends was increased with the increase of PCL content. The decomposition temperature at maximum decomposition rate were increased and the char yield were decreased with the PCL content. In addition, the kinetics of thermal degradation were determined using Kissinger Model.
