- Настоящее изобретение предлагает способ полимеризации для получения полимеров с узким молекулярно-массовым распределением. Указанный способ включает введение мономера и инициатора в реактор с использованием режима подачи мономера и режима подачи инициатора, где указанные режимы подачи таковы, что отношение концентрации мономера к концентрации инициатора определяют в соответствии с кинетическим уравнением полимеризации, отражающим зависимость выбранной степени полимеризации от концентрации мономера, концентрации инициатора, реакционной температуры и коэффициента эффективности полимеризации для получения примерно постоянной степени полимеризации в ходе полимеризационного процесса. Коэффициент эффективности полимеризации используют для учета отклонений от идеальных кинетических уравнений.
