A clay-filled polyolefin composition and process for making it are disclosed. The process involves treatment of a non-acid-treated smectite clay with a Ziegler-Natta catalyst in the presence of a hydrocarbon and subsequent polymerization of an olefin in the presence of the treated clay and an organoaluminum cocatalyst. Results indicate that filled compositions produced by this process contain exfoliated clay.

Показаны глин-zapolnennye состав и процесс полиолефина для делать его. Процесс включает обработку нон-кислот-obrabotanno1 глины smectite с катализатором Ziegler-Natta in the presence of углерод и затем полимерность олефина in the presence of обработанная глина и cocatalyst organoaluminum. Результаты показывают что заполненные составы произведенные этим процессом содержат exfoliated глина.
