| Abstract: | The effect of photoinitating (camphorquinone/amines) system concentration and sample thickness on the photopolymerization of triethyleneglycol dimethacrylate/2-hydroxypropyl methacrylate has been investigated. The rate of photopolymerization reaches a maximum and then decreases as the concentration of photoinitiating system increases. This effect has been intepreted as inner filter effect. This revised version was published online in July 2006 with corrections to the Cover Date. |
