Metallocenes promise to fix all that, and to deliver new properties to boot. The catalysts act rather like tiny molecular robots to let chemists control the alignment and structure of polymer chains.

Metallocenes — 'sandwich' compounds with metals facially bonded to two cyclopentadiene ligands — are very well-known. Their discovery prompted a renaissance in organometallic chemistry and ...

A slow economy isn't stopping Houston firms ExxonMobil Chemical Co. and Total Petrochemicals USA Inc. from stepping up their efforts in metallocene polyolefins. ExxonMobil launched production ...

Metallocenes, a type of organometallic compound, are known for their versatility and special "sandwich" structure.

Using the method, the researchers found that doping with electron-deficient metallocenes, such as those with a cobalt core, results in CNT s with more positively charged electron “holes” than ...
