Chemorheology and thermomechanical characteristics of benzoxazine‐urethane copolymers
The results reveal that a processing window of the BA‐a/PU mixtures is widened with the increasing urethane prepolymer fraction, that is, the liquefying temperature is lowered and the gel point shifted to higher temperature with the amount of the PU.
