Abstract

Сущность изобретения: каталитическая система для полимеризации диолефиновых мономеров состоит из соли лантаноида, металлоорганического соединения металла, относящегося к I, II, и III группам периодической системы элементов, и металлоорганического соединения бора. Получаемые полимеры имеют высокий уровень содержания 1,4-звеньев и изменяемое при необходимости соотношение между звеньями 1,4-цис и 1,4-транс, а также узкое молекулярно-массовое распределение.
