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 ...
