Abstract
The present disclosure relates to a Ziegler-Natta catalyst system with self-extinguishing properties suitable for olefin polymerization. The catalyst system of the present disclosure comprises a pro-catalyst, a co-catalyst, and an external donor having a mixture of a selectivity control agent and an activity control agent. The catalyst system of the present disclosure is adapted to prevent the temperature of the polymerization reaction to go beyond the softening temperature of the polymer, thereby exhibiting the self-extinguishing properties.
Claims18
A Ziegler-Natta catalyst system with self-extinguishing properties suitable for olefin polymerization, said catalyst system being characterized by having a fluorinated ester of a long chain fatty acid with C4-C20 carbon atoms as an activity limiting agent.
