    Abstract: The present invention relates to monofunctional benzoxazines having non-benzoxazine functional groups thereon. Polymers of benzoxazine can be formed from the monomers through functional group polymerization as well as benzoxazine polymerization utilizing the same or different mechanisms. The functionalized benzoxazine materials are high performance polymers having glass transition temperature about 200° C and which exhibit other desirable properties such as increase of char yield without a significant increase in viscosity of the monomer. Furthermore, the functionalized benzoxazine monomers can be copolymerized with other monomers such as epoxy. The benzoxazine copolymers exhibit toughness, processability, and excellent thermal properties.

    Abstract: Benzoxazine monomers, oligomers and polymers are desirably modified by adding pendant functional groups to either the amine or phenolic reactants. These pendant functional groups can be activated at temperatures generally from about 25 DEG C to about 300 DEG C to form chemical bonds between said benzoxazine monomers, oligomers and polymers. The additional chemical bonds increase the thermal stability of benzoxazine polymers such that they can withstand higher use temperature, act as more effective flame barriers, or result in higher amounts of char if used as a precursor to high temperature (600-1000 DEG C reaction condition) chars.

    Abstract: A curable resin composition containing a blend of multifunctional benzoxazines, and composite materials derived therefrom. The benzoxazine blend contains the combination of (A) a difunctional benzoxazine component and (B) a multifunctional benzoxazine component with functionality of greater than 2. Cured matrix resins and cured composite materials containing such benzoxazine blend exhibit a significant retardation in the rate of organic solvent uptake as compared to the same cured matrix resins and composite materials without component (B).

    Abstract: Disclosed herein are monofunctional benzoxazine compounds having at least one electron-withdrawing group. The monofunctional benzoxazine compounds may be combined with one or more multifunctional benzoxazine compounds to form a unique benzoxazine blend. This benzoxazine blend may be combined with additional components such as catalysts and toughening agents to form a curable resin composition suitable for forming resinous films or composite materials. The presence of monofunctional benzoxazine improves the processability of the benzoxazine-based resin composition by reducing the viscosity of the resin composition, and results in improved tack and drape in the films and composite materials formed from the composition without the loss of modulus in the cured resin.

    Abstract: 提供一种含苯并环丁烯官能团的苯并噁嗪单体及其合成方法和应用。所述含苯并环丁烯单体的苯并噁嗪单体可由两种路线合成。其一是采用含氨基的苯并环丁烯和酚类化合物以及甲酸（或者多聚甲酸）为原料，通过洗涤、萃取等方法提纯分离，得到目标单体。其二是以4-羟基苯并环丁烯和含伯胺类化合物以及甲酸（或者多聚甲酸）为原料，通过洗涤、萃取等方法提纯分离，得到目标单体。该苯并噁嗪单体在一定温度下具有较低的粘度，可以通过加热或者催化剂催化的方法进行固化。固化后得到的树脂具有优良的热稳定性、机械性能、以及极低的吸湿性，可以用作电子封装材料、耐高温阻燃材料、高性能复合材料、航空材料等。
