Through the TG curve ( Fig. 4) was found in either the BOZ-1 high purity products or their untreated crude product decomposition rates were higher than those of BOZ-3, and 800℃the residual carbon rate is far lower than that of BOZ-3, BOZ-1 heat resistance than BOZ-3, this explained to a certain extent the benzoxazine resin prepolymer. Xi Bingji and methoxy not only produces a synergistic effect to increase the curing product heat resistance, but will reduce its thermal performance. At the same time, the author found that crude product initial decomposition temperature while the higher purity product is low, but its heat resistance is high purity products, from Figure 4, it is not difficult to find whether BOZ-1 or BOZ-3 crude product decomposition rate is lower than 800℃high purity products, the residual carbon rate is more than the product of high purity. This is because the crude product containing benzoxazine compound monomer oligomers, oligomers containing hydroxyl group, and the hydroxyl presence can accelerate benzoxazine resin prepolymer curable, make originally below the decomposition rate cure rate increased and eventually to curing, decomposition supplemented, curing extent increase can be effective increase the cured product of cross-linking density, increasing carbon layer structure and protection layer, improve the curing thermostability, and ultimately reflected in high carbon residue rate and low decomposition rate, BOZ-1 ' and BOZ-3 ' phased weightlessness effectively confirmed the hypothesized.

Through the TG curve (FIG. 4) found that both BOZ - 1 high purity products or the untreated coarse product decomposition rate are higher than BOZ - 3, and the 800 ℃ residual carbon rate is far lower than BOZ - 3, BOZ - 1 heat resistance than BOZ - 3, this, to a certain extent, shows benzoxazine resin of prepolymerization body on allyl and methoxyl group not only cannot produce synergistic effect increase its curing product heat resistance, it will reduce its thermal performance. At the same time, the author found that coarse product of the initial decomposition temperature although higher purity products is low, but its heat resistance is high purity products, from in figure 4 is not difficult to find whether BOZ - 1 or BOZ - 3 the coarse product decomposition rate lower than high purity products, 800 ℃ while the ratio of the carbon residue were higher than the high purity products. This is because the coarse product contains benzoxazine compounds monomer oligomer, oligomers containing hydroxyl, and the existence of hydroxyl can accelerate benzoxazine resin of prepolymerization body curing, make originally below the decomposition rate of the curing rate increase and eventually to curing is given priority to, decomposition is complementary, the increase of the degree of cure can effectively increase curing product crosslinking density, increase carbon layer structure and protective layer, improve the curing product heat resistance, and finally reflected in high carbon residue rate and low decomposition rate, BOZ - 1 "and BOZ - 3" phases weightlessness is powerful confirmed that the author's speculation.
