The photocrosslinking of PVC with benzophenone as photoinitiator and trimethylolpropanetrimethacrylate (TMPTMA) as crosslinking agent has been examined. Various factors affecting the crosslinking process (the concentration of photoinitiator and crosslinking agent, irradiation temperature and time, atmosphere, plasticizer) were investigated. Gel yield increased with increased irradiation time and TMPTMA content. Crosslink density increased at higher irradiation temperature and TMPTMA content. The rates of PVC crosslinking reaction were enhanced with the plasticizer.
