一种新的光固化树脂齐聚物合成用催化剂

针对常规催化剂体积大、活性低、反应时间（t)长、粘度及残余量大等缺点，设计合成了一种新的催化剂-三乙基烯丙基氯化胺，以用于SL（StereoLithography)法光固化树脂专用齐聚物的制备，因为新的催化剂带有不饱和双键，所以在紫外光固化时可参与聚合，残余量少，并且其催化活性高，可在较低温度（80-90℃）及较短时间（2h)内完成反应，因此降低了体系的粘度。

New Kind of Catalyst Used for Preparing Oligomer for Light-Curable Resin

The shortcomings of conventional catalyst are bulky and low activity,that lead to long reaction time, large relic volume and high viscosity. A new kind of catalyst-triethyl-allyl ammonia chloride is designed and developed that can be used for preparing a proper oligomer for SL light-curable resin. Owing to unsaturated double bond of the new catalyst, it can participate the reaction when UV solidify,at the same time,the relic volume is decreased. The reaction can be finished at lower temperature（80～90　℃） and shorter time（2 h) by the high activity of the new catalyst, and the viscosity of resin is also decreased.
