초록 | A monitoring technique of UV polymerization using a quartz crystal oscillator was explained and applied to the polymerization of 2-hydroxyethyl methacrylate with a photoinitiator of 1-chloroanthraquinone. The resonant frequency of the oscillator indicates the polymerization degree. With the different initiator concentrations and UV irradiations, the resistance increase was measured and compared with the measured outcome from FT-IR and GPC. The experimental results indicate that higher concentration of the initiator gives larger increase of the resistance and longer irradiation leaves higher ultimate resistance. The higher resistance means higher degree of polymerization as observed with FT-IR and GPC. This demonstrates the effectiveness of the quartz crystal oscillator for the in-line measurement of polymerization degree. |
