Radiation Induced Polymerization of Isoprene

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...

Iron-catalyzed polymerization of isoprene and other 1,3-dienes.

Polymerization of Isoprene by Using Benzyl Diethyldithiocarbamate as an Iniferter

The polymerization of isoprene through the use of benzyl N,N-diethyldithiocarbamate (BDC) as an iniferter was investigated. The monomer concentration used was kept constant at 2.8 mol/L while the BDC concentration was varied. The polymer product was characterized by Fourier Transform Infrared Spectroscopy (FTIR), Proton Magnetic Resonance (H-NMR), and Differential Scanning Calorimetry (DSC) and...

Immobilization of yeast cells by radiation-induced polymerization.

Radiation-induced polymerization method was applied to the immobolization of yeast cells. The effects of irradiation, cooling and monomer, which are necessary for polymerization, were recovered completely bu subsequent aerobic incubation of yeast cells. The ethanol productive in immobilized yeast cells increased with the increase of aerobic incubation period. The growth of yeast cells in immobi...
