A method of obtaining modified phthalonitriles comprising organophosphorus fragments, binding agents based thereon, and products produced with the use thereof, can be used in a variety of fields—from aircraft and automobile manufacturing to producing polymer composite materials. The method makes it possible to produce phthalonitrile monomers comprising organophosphorus fragments from simpler and cheaper reagents and to obtain them as individual substances, simplifying the process of synthesis, reducing the glass transition temperature of monomers and increasing the thermal oxidation stability of hardened polymers. The phthalonitrile monomer modified with organophosphorus fragments is characterized by the following general formula:
wherein R is a radical selected from the group comprising aryl, alkyl, aryloxy or alkyloxy substituents; and X is a divalent aryl substituent selected from a group comprising phenylenes and naphthylenes. Also disclosed is a method of obtaining the modified phthalonitrile monomer, a binder, and a prepreg based on the same.
一种获得含有有机磷基团的改性邻二氰酸酯的方法,以及基于该方法的结合剂和使用它们生产的产品,可以用于各种领域——从飞机和汽车制造到生产聚合物复合材料。该方法使得从更简单和更便宜的试剂中获得含有有机磷基团的邻二氰酸酯单体成为可能,并将它们作为单独物质获得,简化了合成过程,降低了单体的玻璃转变温度,并提高了硬化聚合物的热氧化稳定性。含有有机磷基团改性的邻二氰酸酯单体的一般式如下:其中R是从苯基,烷基,芳氧基或烷氧基取代基组成的基团;X是从苯基和萘基组成的二价芳基取代基。还公开了一种获得改性邻二氰酸酯单体、粘合剂和基于其的预浸料的方法。
