Book Description
Synthesis, Characterization and Polymerization Reactivity of Niobium-based Metal Complexes
Olefins Polymerization Reactivity of Niobium-Based Metal Complexes
Author: Yogesh Raghunath Patil
Publisher: LAP Lambert Academic Publishing
ISBN: 9783846510292
Category :
Languages : en
Pages : 192
Book Description
This book describes the synthesis and characterization of niobium-based metal complexes and their usefulness as catalysts for the polymerization of ethylene, norbornene, beta pinene and vinyl monomers. The polymerization of above described monomers was studied using niobium complexes based on N, N dialkylcarbamates, mixed chloro alkoxides, simple oxygen-containing ligands and the starting material for the preparation of such derivatives, i.e. NbCl5.Niobium N, N-dialkylcarbamates exhibited high activity for polymerization of ethylene when activated with TMA-depleted MAO and 1,2-dichloroethane as activator working at 1 bar ethylene pressure. These novel catalytic systems resulted very active in Ring-opening metathesis polymerization (ROMP) of norbornene (NBE)with the highest activity never reported up to now for any transition metal catalysts. The dinuclear niobium compounds and simple oxygen-containing derivatives of niobium pentachloride were tested for ethylene polymerization and produced satisfactory results.In this context, it was found that easily accessible NbCl5 works as an excellent catalyst for the polymerization of β-pinene styrene and butylvinyl ethers

Synthesis and Polymerization of Metal-Containing Monomers
Author: Anatoly D. Pomogailo
Publisher: CRC Press
ISBN: 1351093959
Category : Science
Languages : en
Pages : 159
Book Description
This book overviews methods for the synthesis of metal-containing monomers with various types of metal bonds to the organic moiety of the molecule, such as ionic, covalent, donor-acceptor, and others. Published data on homopolymerization, copolymerization, and graft polymerization of these monomers are generalized. Synthesis and Polymerization of Metal-Containing Monomers discusses features typical of the molecular and structural organization of the resulting metal-containing polymers, their properties and the associated major applications, such as catalytical and biological activity, electrophysical characteristics, and thermal resistance.
