Low‐Temperature Polymerization of Ethylene
Angewandte Chemie International Edition in English, 1963AbstractA two‐component organometallic catalyst of composition CH3TiCl3·CH3AlCl2 effects high‐speed polymerization of ethylene in the presence of chlorinated hydrocarbons at low temperatures. The catalyst does not undergo any alteration in the process. In contrast to the Ziegler catalysts, the titanium remains quadrivalent.

POLYMERIZATION OF ETHYLENE WITH SOLUBLE CATALYSTS
1967ABSTRACT The use of soluble catalytic systems formed by Al(C2H5)3 and Ti (O-iC3H7)4 in the polymerization of ethylene, yields different results depending on the ratios of the components and on their methods of preparation. When solutions of the two components are mixed, at room temperature and under inert atmosphere (N2), followed by the addition of ...

Confinement-Induced Polymerization of Ethylene
The Journal of Physical Chemistry C, 2011Density functional theory (DFT) calculations show changes in geometric and electronic properties of an ethylene molecule confined between two metal surfaces and its conversion into a radical anion ...

Superhydrophobic Polyethylene Films by Catalytic Ethylene Polymerization
Journal of Adhesion Science and Technology, 2008Polyethylene films were grown on a flat silica surface modified by the bis(imino)pyridyl iron(II) catalyst during ethylene polymerization in an organic solvent. The resulting films show under certain polymerization conditions superhydrophobic properties.

Polymerization of ethylene glycol dimethacrylate
Journal of Polymer Science, 1959AbstractIn the polymerization of ethylene glycol dimethacrylate (EDMA), the content of pendant double bonds (PDB) in the polymer was found to be lower than expected, hence it was deduced that the intramolecular cyclizations occurred in the polymerization.

2‐Phosphanylphenolate Nickel Catalysts for the Polymerization of Ethylene
Chemistry – A European Journal, 2003AbstractThe previously unknown methallylnickel 2‐diorganophosphanylphenolates (RPh, cHex) were synthesized and found to catalyze the polymerization of ethylene. To explore the potential for ligand‐tuning, a variety of P‐alkyl‐ and P‐phenyl‐2‐phosphanylphenols was synthesized and allowed to react with [Ni(cod)2] (cod=1,5‐cyclooctadiene) or with NiBr2 ...

Organocatalytic polymerization of ethylene carbonate
Materials Today Communications, 2015Abstract Organocatalytic polymerization of ethylene carbonate ( EC ) with 3-phenyl-1-propanol ( 3PP ) or triethylene glycol ( TEG ) as initiator and 1,5,7-triazabicyclo[4.4.0]dec-ene ( TBD ) as catalyst using a mono-mode microwave reactor results in poly(ether carbonate) s with M n (GPC) values between 2200 and 3100 g/mol and a ratio of ethylene ...

Continuous polymerization of ethylene oligomers
Chemistry and Technology of Fuels and Oils, 1986The authors conduct experiments which demonstrate the feasibility of using ethylene oligomers as raw material in the production of M-9SV synthetic lube oil. Basic characteristics of the starting materials used in the studies are given. The polymerization catalyst was AlCl/sub 3/.
