Description

Изобретение относитс  к области синтеза полнимидов, а именно, к синтезу алкилароматических полиимидов. Эти полимеры перерабатываютс  прессованием, литьем под давлением и другими способа ми и дают прочные издели , сохран ющие высокие механические и электрические характеристики в услови х высоких температур . Полимеры наход т применение в электро- в радиотехнической промыш ленности. Известен способ получени  алкиларо матических полнимидов f 1 реакдией диангидридов 3,3 , 4,4 - дифенилоксид тетракарбрновой, 3,3 , 4,4 - дифенилсульфонтетракарбоновой , пиромеллитовой и других тетракарбоновых кислот и диаминов , таких как гексаметилендтшмин, октаметвленд амин, декаметиленднамнн, ксилилеидиамвн, 9,9 би(-(4-«минофеШ1л )-фпуорен в других, одностадвйной высокотемпературной поликонденсацией. Следует, однако, отметить, что при получении полиимвдов этим способом из-за происход щих при высоких температу: - pax обменных реакций между аминогруппами и имидными циклами гютруднено регулирование микроструктуры сополимеров, т, е. практически исключаетс  создание блоксополиимидов. Известен также способ получени  алкилароматических полииь идов 2jHa основе диангидридов тетракарбоновых кислот и алифатических диаминов, таких как гексаметилендиамин, октаметилендиамин и других, двухстадийнсй поликонденсацией через промежуточное образование полиамидокислоты с ее последующей термической или химической циклизацией . Недостатком этого способа  вл етс  то, что полиимиды, полученные таким образом, имеют низкую молекул рную массу, что обусловлено побочной реакцией солеобразовани  между аминами и карбоксильными группами полиамидокислот . Из-за низкой молекул рной мае3 сы гакие попиимиды характеризуютс  ведостаючным уровнем прочности и термических свойств. Целью данного изобретени   вл етс  увеличение молекул рной массы полиимид и регулирование микроструктуры конечно го продукта. Это достигаетс  тем, что в реакции поликонденсации диангидрида тетракарбоНовой кислоты используетс  силилированный алифатический диамин при эквимол рном соотношении исходных веществ.
