Reaction of benzoxazine /phenolic mixed resin is investigated . Viscosity-temperature characteristics, kinetics of reaction and co-reaction mechanisms of the mixed resins are studied. Experimental results indicate that the benzoxazine resin may be mixed at almost any ratio with phenolic resin. Mixed resin FBZ/4 with 40% of the benzoxazine presents high reactivity compared with other ratio mixed resins by viscosity-temperature characteristics and DSC analysis.
