UV 광 중합 반응의 진행정도를 near-IR 분광학적 방법을 사용하여 관찰하였다. 광중합반응의 반응체는 4차 암모늄염을 포함하고 있는 아크릴 모노머를 사용하였으며 광 개시제로는 Darocur 1174를 사용하였다. 반응의 진척도는 광중합 반응의 정도를 나타내 주는 척도가 되는 중합 반응체인 아크릴 모노머의 -C
The extent of UV-curing photo-polymerization reaction was monitored by near-IR spectroscopic method. Acrylates containing quaternary ammonium salts and Darocur 1173 were used as reactive monomer and a photo initiator, respectively. The extent of photo-polymerization reaction was obtained from the conversion ratio of acrylate double bond calculated from the intensities of measured bands at 1615 nm and at 2105 nm. Near-IR spectroscopic methods can be an useful tool for the monitoring of the progress of photo-polymerization.
