Ziegler-natta catalyst for tuning MWD of polyolefin, method of making, method of using, and polyolefins made therewith

   
   

A new synthesis of a Ziegler-Natta catalyst uses a multi-step preparation that includes treating a magnesium dialkoxide compound with two halogenating/titanating agents, the second stronger than the first, an organoaluminum preactivating agent, and a heat treatment. The catalyst may be used in the polymerization of olefins, particularly ethylene, to control the molecular weight distribution of the resulting polyolefins.

Новый синтез катализатора Ziegler-Natta использует multi-step подготовку вклюает обрабатывать смесь с 2 веществами halogenating/titanating, вторая сильную чем первое, вещество organoaluminum preactivating, и обработку dialkoxide магния жары. Катализатор может быть использован в полимерности олефинов, определенно этилене, для того чтобы контролировать распределение молекулярного веса приводя к полиолефинов.
