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

open access: yesQuímica 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 ...

Eighty years of macromolecular science: from birth to nano-, bio- and self-assembling polymers—with slight emphasis on European contributions [PDF]

open access: yes, 2018
A definition of macromolecular science (as opposed to polymer science and engineering) is given, from which the year 1930 is derived as the year of its birth. The scope of treatment of this paper will be limited to solid technical polymers.

Ziegler-Natta catalyst alteration

open access: yes, 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.
