摘要:
The object of the invention is a process for the preparation of olefin polymers using a modified Ziegler catalyst. As modifications compounds are used which contain as the only functional groups one or two tertiary carboxylic acid amide groups or a urea grouping four times substituted at the nitrogen atoms. Polymers are obtained which confer special mechanical properties on the molded articles prepared therefrom.
摘要:
The invention relates to a process for the preparation of olefin polymers using a modified Ziegler-catalyst. As modifiers cyclic dipeptides are used. Polymers are obtained in a high yield having good crystallinity and good color quality.
