Preparation method of bisphenol A benzoxazine resin with high stability

A preparation method of bisphenol A benzoxazine resin with high stability is characterized in that bisphenol A, arabino compounds and primary amine react to synthesize the benzoxazine resin by taking a transition metal complex as a catalyst in the presence of organic solvents or inorganic solvents....

description A preparation method of bisphenol A benzoxazine resin with high stability is characterized in that bisphenol A, arabino compounds and primary amine react to synthesize the benzoxazine resin by taking a transition metal complex as a catalyst in the presence of organic solvents or inorganic solvents. The ring-forming rate, the pre-polymerizing rate and the molecular weight distribution of the benzoxazine resin can be stably controlled. The benzoxazine resin has stable physical and chemical storage stability and less possibility of separating out; and a condensate of the benzoxazine resin has excellent high-temperature resistant performance, mechanical property and flame-retardant performance.
