Таблица 3Table 3
Таблица 2 Пример 2. Осуществл етс аналогично примеру 1, отвердитель 4,4-бис-(3-аминофе нилсульфонат) - дифенилсульфон вводитс н в стехиометрическом количестве, а 0,85 о стехиометрии, т. е. на 100 вес. ч. смолы ЭДберут на 67,5, а 57,4 вес. ч. отвердител . Пример 3. Осуществл етс аналогично примеру 1, но отвердитель вводитс в количестве 1,5 от стехиометрии, т. е. на 100 вес. ч. смолы ЭД-5 берут не 67,5, а 101 вес. ч. отвердител . Пример 4. К 100 вес. ч. триглицидного эфира парааминофенола (содержание эпоксидных груии 35%), разогретого до 80°С, добавл ют 115 вес. ч. тонкоизмельченного 4,4бис- (З-аминофенилсульфонат) - дифенилсульфона . После полного растворени отвердител в смоле композицию заливают в предварительно нагретые формы и отверждают при 120°С 2 ч; при 140°С 2 ч; ири 160°С 8 ч. Пример 5. К 100 вес. ч. диглицидного эфира резорцина (содержание эпоксидных групп 31%), разогретого до 80°С, добавл ют 100 вес. ч тонкоизмельченного 4,4-бис-(3-амИнофенилсульфонат ) - дифенилсульфона. После полного растворени отвердител в смоле композицию заливают в предварительно нагретые формы и отверждают при 120°С 2 ч, ири 2 ч; при 160°С 8 ч. Свойства композиций по примерам 2-5 привод тс в табл. 4. Таблица 4Table 2 Example 2. Carried out analogously to example 1, the hardener 4,4-bis- (3-aminophenylsulfonate) - diphenylsulfone is introduced in stoichiometric amount, and 0.85 o stoichiometry, i.e. per 100 wt. including tar ED will be 67.5, and 57.4 weight. h. hardener Example 3. Carried out as in Example 1, but the hardener is introduced in an amount of 1.5 times the stoichiometry, i.e. per 100 weight. h. resin ED-5 take not 67.5, and 101 weight. h. hardener Example 4. To 100 weight. including triglycidic ester of para-aminophenol (epoxy resin content 35%), heated to 80 ° C, 115 weight% was added. including finely ground 4,4bis- (Z-aminophenylsulfonate) diphenylsulfone. After the hardener is completely dissolved in the resin, the composition is poured into pre-heated forms and cured at 120 ° C for 2 hours; at 140 ° C for 2 h; Irie 160 ° C 8 h. Example 5. To 100 weight. including resorcinol diglycid ester (content of epoxy groups 31%), heated to 80 ° C, add 100 wt. finely ground 4,4-bis- (3-aminophenylsulfonate) diphenylsulfone. After complete curing of the hardener in the resin, the composition is poured into pre-heated forms and cured at 120 ° C for 2 hours, and 2 hours; at 160 ° C for 8 hours. The properties of the compositions of examples 2-5 are given in table. 4. Table 4
