Description
в атмосфере азота в течение 30-45 мин до легкого загустени . Затем смесь заливают в формы из силикатного стекла, номещают их в термостат с циркулирующим нотоком воздуха и провод т -полимеризацию но режиму , указанному в примере 1.under nitrogen for 30-45 minutes until slightly thicken. Then the mixture is poured into silicate glass molds, but they are placed in a circulating air-condition thermostat, and the polymerization is carried out according to the mode indicated in Example 1.
Пример 3. К смеси 12 г (60 вес. %) адамантилметакрилата и 8 г (40 вес. %) ДМХМФ добавл ют 0,1 (0,5 вес. %) пере киси бензоила, перемешивают до полногоExample 3. To a mixture of 12 g (60 wt.%) Of adamantyl methacrylate and 8 g (40 wt.%) Of DMCMP, add 0.1 (0.5 wt.%) Benzoyl peroxide, mix until complete
растворени инициатора и провод т форполимеризацию при 60°С -при перемешивании в атмосфере азота в течение 30-45 мин до легкого загустевани . Затем полимеризацию провод т в формах по указанному в примере 1 режиму.dissolving the initiator and carrying out the prepolymerization at 60 ° C with stirring under a nitrogen atmosphere for 30-45 minutes until easy thickening. Then the polymerization is carried out in the forms specified in example 1 mode.
Свойства полученных сополимеров приведены в таблице. Огнестойкость испытывали по методу «Огнева труба по ГОСТ 170 88-71.The properties of the obtained copolymers are shown in the table. Fire resistance was tested by the method of “Fire tube according to GOST 170 88-71.
Таким образом, изобретение позвол ет получать термостойкие, не растворимые в органических растворител х сополимеры.Thus, the invention makes it possible to obtain heat-resistant copolymers insoluble in organic solvents.
