    • 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.
    • 本发明涉及其上具有非苯并恶嗪官能团的单官能苯并恶嗪。 苯并恶嗪的聚合物可以通过官能团聚合由单体形成,也可以使用相同或不同的机理形成苯并恶嗪聚合。 官能化的苯并恶嗪材料是玻璃化转变温度约为200℃的高性能聚合物,并且其表现出其它所需的性能,例如增加焦炭产率而不显着增加单体的粘度。 此外,官能化的苯并恶嗪单体可以与其它单体如环氧树脂共聚。 苯并恶嗪共聚物具有韧性,加工性和优异的热性能。

    • 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.
    • 希望通过向胺或酚类反应物中加入侧链官能团来修饰苯并恶嗪单体,低聚物和聚合物。 这些侧基官能团可以在通常约25℃至约300℃的温度下活化,以形成所述苯并恶嗪单体,低聚物和聚合物之间的化学键。 额外的化学键增加了苯并恶嗪聚合物的热稳定性,使得它们可以承受更高的使用温度,作为更有效的阻燃剂,或者如果用作高温的前体(600-1000℃的反应条件) )字符
