“…The first exotherm in the temperature range of about 240-250 C is attributed to the curing reaction among benzoxazine monomers. The second exotherm is attributed to the reaction between benzoxazine and epoxy resins, which occurs at temperatures of about 290-300 C [21]. We have previously investigated Table 1 Characteristics of the crosslinking and T g data of the benzoxazine-epoxy systems after curing at 180 C for 3 h and post-curing at 220 C for 3 h.…”

“…Reactive blends of BA-a are finding increasing interest in research and the use of epoxy co-monomers 17,18 are pre-eminent, forming the basis of commercial blends such as the Epsilon resins from Henkel 19 ; the addition of epoxy improving the processing characteristics of the benzoxazine and related ternary blends have been explored using phenolic co-monomers 20,21,22 .…”

“…In addition, there is no by-product generated when curing that leads to no void in the final products. Alloying the brittle polybenzoxazine with other flexible monomers or polymers have been reported to enhance its crosslink density and mechanical properties in many blending systems such as benzoxazine/epoxy copolymer, 7,9,10 benzoxazine/ epoxy/phenolic ternary systems, [11][12][13] poly(benzoxazine-urethane) alloys, 8,[14][15][16] polybenzoxazine/dianhydride copolymer, 17 polybenzoxazine/ polycaprolactone blends. Moreover, it has been reported that the polymer possesses high thermal stability, high glass transition temperature (T g ) with low water absorption and near zero shrinkage or expansion.…”
