В колбу с обратны.м холодильником помещают 9,6 г (0,1 моль) 3,5-диметилниразола и 7,2 (0,1 моль) акриловой кислоты. Смесь нагревают нри 130-140° С в течение 5 Ч- После охлаждени реакционна смесь кристаллизуетс .9.6 g (0.1 mol) of 3,5-dimethyl-nerazole and 7.2 (0.1 mol) of acrylic acid are placed in a flask with inverse fridge. The mixture is heated at 130-140 ° C for 5 hours. After cooling, the reaction mixture crystallizes.

Полученные соедииени были иснрльзоианы в качестве отвердителей в композици х гор чего отверждени на основе эиоксидиой днановой смолы ЭД-20.The resulting compounds were synthesized as hardeners in hot curing compositions based on ED-20 eoxydioxy resin.
Испытани показали, что оптимальное со.аержанне указанных аддуктов в эпоксидной композиции составл ет 4-13 вес. %.Tests have shown that the optimal co.anerx of these adducts in the epoxy composition is 4-13 wt. %
Эиоксидмые композиции готовили раствореиием отвердител в смоле ЭД-20 при 70-80° С- Были приготовлены по три.композиции , отличающиес содержанием отвердител (5,9, 13 вес. %). Кажда композици подвергалась отверждению в термостате при 150°С.Eioxide compositions were prepared by dissolving hardener in ED-20 resin at 70-80 ° C. Three compositions were prepared, each with a hardening content (5.9, 13 wt.%). Each composition was cured in a thermostat at 150 ° C.
Характеристики получаемых комнозицнй с использованием соединений по изобретению и известного отвердител представлены в таблице.The characteristics of the obtained carnose cells using the compounds of the invention and the known hardener are presented in the table.
