| Abstract: | High density polyethylene has been photo-crosslinked in the molten state by using benzoin dimethyl ether as photoinitiator and trisacryloyloxyethyl isocyanurate (TAEIC) as crosslinking agent . Several factors affecting the crosslinking process , such as dosage of the photoinitiator and crosslinking agent , irradiation temperature and time , and UV light intensity have been examined. It has been found that benzoin dimethyl ether is a very good photoinitiator with high initiation efficiency and the TAEIC can greatly improve crosslinking efficiency . In addition , it has been verified that the irradiation time , UV light intensity and temperature have obvious effects on the degree of crosslinking of PE. |
