Analysis of polymerization behavior of multifunctional monomer with limited wave length and laser.

到目前为止，VL固化复合树脂已采用商用可见光装置进行聚合。然而，VL单元的波长面积对CQ的自由基产生机理影响的报道很少，因此，本研究使用波长为473 nm的激光单元和商用VL单元。并对各因素对聚合行为的影响进行了对比考察。由此得出以下结论：1.在40s的照射下，VL单元的聚合速率高于激光单元。因此，认为能量大小与聚合速率有关。激光装置的聚合物分解活化能大于商用VL装置的聚合物分解活化能。认为聚合引发剂的浸出能力分别取决于VL固化树脂的转化率。

Up to now, the commercial visible light unit have been used for the VL cure composite resin to be polymerized. However, there are few reports which the wave length area of VL unit exerts the influence on the radical generation mechanism of CQ.Therefore, in this research, the laser unit of the wave length of 473nm and the commercial VL unit was used. And, the comparison examination of the influence on the polymerization behavior was done. The following conclusions were as a result.1. In the irradiation of 40 seconds, polymerization rate was higher in case of VL unit than that of the Laser unit. Thus, it was suggested that the amount of energy relate to the polymerization rate.2. The polymer decomposition activated energy by the laser unit was larger than that of the commercial VL unit.3. It was recognized that the leachabitity of polymerization initiator depended on the degree of conversion of VL cured resin respectively.
