Neodymium based ones are popular in the rubber industry because they give a very high cis microstructure and have a pseudoliving character that is not often found in them.
Neodymium based ones are popular in the rubber industry because they give a very high cis microstructure and have a pseudoliving character that is not often found in them. Homogeneous betaine ones can be derived from butadiene zirconocene precursors, and vanadium-based (*) homogeneous ones have delta sites that constitute chiral pockets for si-propene molecules. They work by forming a pi complex at a vacant coordination site, allowing for the accommodation of a propylene molecule to add to a chain. The most well-known of them is a mixture of titanium chloride and alkyl-aluminum. FTP, name these molecules that catalyze the polymerization of olefins, named after their German and Italian discoverers.
