Polimerização 1,4-cis de butadieno com sistemas catalíticos Ziegler-Natta à base de neodímio

Química Nova, 2004
Nowadays the catalyst systems based on neodymium are the ones most used in the high cis polybutadiene production. These systems contain a neodymium compound (catalyst), an alkylaluminium compound (cocatalyst) and a halogen compound (halogenating agent ...

Ziegler-Natta catalyst alteration

, 2017
Ziegler-Natta (ZN) catalysts are among the most important catalysts for the industrial production of plastics. The main components of ZN catalysts are TiCl4 in combination with an organic aluminum component as a cocatalyst, whereas a wide range of additional components exists which influence the catalyst behavior.
