Dobo was the first to report an immobilization of an enzyme with radiation [17]. Immobilization of enzymes by gamma-ray polymerization and electron beam crosslinking were studied by Kawashima [18] and Maeda [19], respectively. Kaetsu et al. have studied the immobilization of various biofunctional components by gamma-ray polymerization of supercooled acrylates and methacrylates [20-25]. [Pg.87]

An example system is PVC and polyethylene wire and cabling irradiated to improve stresscracking resistance, abrasion resistance, high-temperature properties and flame retardance, via controlled electron-beam crosslinking (Loan, 1977). Additionally electron-beam crosslinking is utilized to impart memory into a polymer system, such as crosslinked PE materials for heat-shrinkable films and pipe applications (Baird, 1977). The control of electron-beam processing has advanced the quality of cell size and shape of PE foams via control of crosslink distribution (Paterson, 1984). [Pg.419]

The electron beam crosslinking of PVC/ENR blends by electron beam irradiation has been extensively reported by Ratnam and coworkers. The influence of MFAs such as trimethylolpropane trimethacrylate (TMPTA), 1,6-hexaediol diacrylate (HDDA) and 2-ethylhexyl acrylate (EHA), as well as acrylated polyurethane oligomer on the 70/30 PVC/ENR blend, was investigated. TMPTA was found to give the blend the best mechanical properties. Studies were also done on the effect of irradiation on various formulations of PVC/ENR blends with doses ranging from 50 to 200 kGy these studies included the influence of various additives on the efficiency of the radiation crosslinking of the blends.

Electron beam crosslinking takes place when very high energy radiation is used to initiate molecular crosslinking in high-density polyethylene. This product is extruded like normal HDPE then taken to an E-beam facility and routed under a beam or ray in the accelerator where it is dosed with a specific amount of radiation to release the hydrogen atoms and cause polymer chains to bond or link to the open carbon sites.

By contrast, beta rays/electron beams have a high dose rate (10 to 10 Gy/min) and low penetration range. High energy doses can be introduced into the material within a fraction of a second to trigger radiation-chemistry reactions. Consequently, thin-walled plastic moldings and films could be considered main applications for electron-beam crosslinking. [Pg.48]
