1. The synthesis of benzoxazine - imide resin was studied, with which the glass cloth laminated sheet was made.

2. Curing shrinkage, temperature and curing enthalpy of benzoxazine based on diphenyl oxide resin were investigated.

3. Allyl-functional benzoxazine is synthesized with the allyl phenol produced by us. And the product is characterized and deduced by H-NMR, FTIR, MS and DSC.

4. The boron-modified benzoxazine was synthesized by formaldehyde, phenol, boric acid and diamine.

5. A single - ring benzoxazine was synthesized by solvent - free method.

6. Curing reaction behaviors of barium-phenolic, ammonia-phenolic, benzoxazine and cyanate ester of novolac were studied by differential scanning calorimetry(DSC) technique and gelatin experiment.

7. Allyl-functional benzoxazine is synthesized by the reaction of allyl phenol, phenyl amines, and formaldehyde.

8. 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.

9. Besides, dynamic mechanical analysis (DMA) and thermal gravitational analysis(TGA)were also performed for the polymer from this novel kind of benzoxazine.

10. Two preparations of bisoxazoline are compared, The principle and properties based on the modification of Phenolic resin and Benzoxazine resin are discussed.

11. Focus on application of polybenzoxazines in industry, the development of the benzoxazine resins in recent years was reviewed from the three aspects in synthesis, modification and curing properties.

12. The thermohardening temperature, chemical heat-resistance and thermomechanical property of the curing material of different types of bisphenol benzoxazine were presented.

13. Through the property test,(/benzoxazine.html) the result shows that the laminates with the diphenyl ether modified by benzoxazine are better than that by phenol.

14. A new glass cloth laminate was prepared by using benzoxazine as liquid cement, alkali-free glass cloth as backing material, and treating with cement dipping, baking and pressing.

15. In this paper, two methods are used to modify MWNT. Three different structure benzoxazine was synthesized by melt method and solution method.
