МРНТИ 61.37.37 №3 (2019Г.) Ахмедов В.Н., Ниязов Л.Н., Рахимов Ф.Ф., Паноев Н.Ш. В работе приведены результаты синтеза мономера винилэтинилтриэтоксисилан на основе доступного промышленного продукта тетраэтоксисилана и винилэтинилмагнийбромида. Определены основные физические свойства методом ИК-, УФ-спектроскопии и разработана методика синтеза, позволяющая получать соединения с высокими выходами без трудоемких дополнительных операций. Полученные новые вещества идентифицированы методами ИК и УФ спектроскопии, определены температура их плавления, показатель преломления, плотность и другие физико-химические параметры. Было изучено влияние исходного соотношения компонентов и природы растворителей на выход полимера при различных температурах и продолжительности реакции. Определено, что скорость реакции увеличивается с увеличением полярности растворителя. Ключевые слова: Мономер, тетраэтоксисилан, винилэтинилмагнийбромид, винилэтинилтриэтоксисилан, поливинилэтинилтриэтоксисилан, ИК-, УФ-спектрокопия, температура кипения, коэффициент переломления, плотность, удельная вязкость
