ве исходных веществ ме.тилтетрагидрофталевый и пропионовый ангидрид. Выход 25%, т.пл. 185-186°С {ацетон эфир , 1:1). Вычислено, %: С 49,93; Н 4,71; се 9,84. С„Н,С€Од Найдено, %: С 49,95; И 4,70; Се9,83. Указанные ангидриды испытывают в качестве отвердителей эпоксидных смо в виде ниэкоплавких смесей с изомети -тетрагидрофталевым ангидридом (изоМТГФА ) . Весовое собтиспоевие А- I : Иэо-МТГФА и А- I И9О-МТГФА-111.

Свойства эпоксидных олигомеров на основе смесей изо-МТГФА с А- I и А-§ в сравнении со свойствами эпоксиполимеров на основе иэо-МТГФА даны в прилагаемой таблице. Из этих данных видно, что полимеры на основе отвердителей А- I и А- Д имеют повышенную деформационную теплостойкость. Остальные свойства на уровне изо-МТГФА. Данные испытаний приведены в таблице. ве смолы ЭД-22 в изс МТ1Фа-А-1 ve of the original substances metiltiltetrahydrophthalic and propionic anhydride. Yield 25%, mp. 185-186 ° C {acetone ether, 1: 1). Calculated,%: C 49.93; H 4.71; All 9.84. C „H, C € Od Found,%: C 49.95; And 4.70; Se9.83. These anhydrides are tested as hardeners of epoxy resin in the form of low melting mixtures with isomet-tetrahydrophthalic anhydride (isoMTHPA). Weights of AI-I: Ieo-MTHPA and A-I I9O-MTHFA-111. Recipe loading, wt.h, .g Epoxy resin ED-22 100 Properties of epoxy polymers on the dependence of iso-MTHPA, c and iso4 System A-1-iso-MTHPA (49,5: 47,5) 97 System A-1- iso-MTHPA (50:50) 100 Curing mode: - 3 h, 150 ° C - 3 h. Properties of epoxy oligomers based on mixtures of iso-MTHPA with A-I and A-§ in comparison with the properties of epoxy-polymers based on e-MTHFA given in the attached table. From these data it is clear that polymers based on hardeners A-I and A-D have an increased deformation heat resistance. The remaining properties are at the level of iso MTHFA. Test data are given in the table. ve resin ED-22 in izs MT1FA-A-1
