Radiation-Induced Polymerization of Vinyl Ethers

METHOCEL Cellulose Ethers as Suspending Agents for Suspension Polymerization of Vinyl Chloride

Anionic Vinyl Polymerization

The concept of anionic polymerization was first developed by Ziegler and Schlenk in early 1910. Their pioneering work on the polymerization of diene initiated with sodium metal set the stage for the use of alkali metal containing aromatic hydrocarbon complexes as initiators for various α-olefins. In 1939, Scott and coworkers used for the first time the alkali metal complexes of aromatic hydroca...

Photo and Radiation Induced Ionic Polymerization

Photo-induced cationic polymerizations of styrene and x-methylstyrene, which are weak electron donors and contain no hetero atom, were carried out in the presence of electron acceptors such as tetracyanobenzene and pyromellitic dianhydride to elucidate the polymerization mechanism initiated through an excited charge transfer interaction. Cyclohexene oxide was also polymerized by photo-illuminat...

Mathematical Model for Vinyl-Divinyl Polymerization

A mathematical model for the crosslinking copolymerization of a vinyl and divinyl monomer was developed and applied to the case of methyl methacrylate and ethylene glycol dimethacrylate batch polymerization. Model results compare favorably to the experimental findings of Li and Hamielec for the system investigated. The model presented utilizes the numerical fractionation technique and is capabl...

Methylenelactide: vinyl polymerization and spatial reactivity effects

The first detailed study on free-radical polymerization, copolymerization and controlled radical polymerization of the cyclic push-pull-type monomer methylenelactide in comparison to the non-cyclic monomer α-acetoxyacrylate is described. The experimental results revealed that methylenelactide undergoes a self-initiated polymerization. The copolymerization parameters of methylenelactide and styr...
