Ethylene polymerization reactions with Ziegler-Natta catalysts. II. Ethylene polymerization reactions in the presence of deuterium

Journal of Polymer Science Part A, 1999
Ethylene polymerization reactions with many Ziegler–Natta catalysts exhibit several features which differentiate them from polymerization reactions of α-olefins: a relatively low ethylene reactivity, higher polymerization rates in the presence of α-olefins, a high reaction order with respect to ethylene concentration, and strong reversible rate ...

Visualization of on-surface ethylene polymerization through ethylene insertion

Science, 2022
Polyethylene production through catalytic ethylene polymerization is one of the most common processes in the chemical industry. The popular Cossee-Arlman mechanism hypothesizes that the ethylene be directly inserted into the metal–carbon bond during chain growth, which has been awaiting microscopic and spatiotemporal experimental ...

Pressure-Induced Polymerization in Solid Ethylene

The Journal of Physical Chemistry B, 2005
Ethylene is the simplest organic molecule containing a double bond and is the starting monomeric unit in the synthesis of polyethylene, one of the most largely produced polymers. Here we report a high pressure infrared study of ethylene at room temperature.
