PHOTOPOLYMERIZATION IN THE MICELLAR SYSTEMSⅡ THE CATALYSIS OF PKT FUNCTIONAL MICELLE

A kind of cationic compounds, having benzophenone end group and various length chain （PKT） （BP-CH;N+R;R’·X;, R&R’ different chain iength alkyl group） were used as photosensitizers. Various BP/TEA systems have been used for study, The efficiency of MMA photopolymerization initiated by them shows PKT>BP in homogeneous water solution and PKT> BP/CTAB in micellar water solution. The results obtained indicate that catalytic effects of PKT type functional micelles are far greater than that of common micelle with the enhancement of polymerization rate over 10 times compared with BP in water solution. The catalytic role, reaction character of PKT, effect of counter ions and retarding effect of oxygen have also been discussed.
