A new monomer containing thermosetting groups of two types, namely, propargyl ether and phthalonitrile, in the structure of the molecule was synthesized and studied. It was found that thermal polymerization was accompanied by the degradation of the monomer with propargyl ether decomposition. This problem can be solved using catalysts based on Cu(i) favoring the polymerization at both the propargyl group and phthalonitrile fragments. The cured monomer has a non-porous structure and high thermal properties (Vicat softening temperature 395 °C, T5% 451 °C). The low viscosity of the melt (<200 mPa s at 120 °C) and low glass-transition temperature (9 °C) of the monomer make it possible to use it for the formation of composite materials by vacuum infusion or injection into a mold.

具有炔丙基和邻苯二甲腈基团的三官能热固性单体

合成并研究了分子结构中含有炔丙醚和邻苯二甲腈两种热固性基团的新型单体。发现热聚合伴随着单体的降解和炔丙基醚的分解。这个问题可以使用基于 Cu(i) 的催化剂来解决，有利于炔丙基和邻苯二甲腈片段的聚合。固化后的单体具有无孔结构和高热性能（维卡软化温度395°C，T5% 451°C）。熔体的低粘度（在 120 °C 时 <200 mPa s）和单体的低玻璃化转变温度 (9 °C) 使其可用于通过真空灌注或注射到模具中形成复合材料.
