| 摘 要： | 研究了异海松酸为单体进行紫外光固化反应的影响因素，采用红外光谱法对双键转化率进行了表征和分析。采用凝胶色谱分析（GPC）、差示扫描量热分析（DSC）和热重分析（TO）等手段对固化膜的性能进行了表征。结果表明：固化过程中双键转化率随光照时间的增加而增加，随引发剂添加量增加先上升后下降；相对固化速率随引发剂用量、光照强度的增加及光照距离的减小而增加。

| Abstract: | The factors of the UV curing reaction were investigated using isopimaric acid as monomer. Conver- sion rate of double bond was characterized and detected by FT-IR analysis. And the obtained UV-cured coating was characterized by gel permeation chromatography （GPC）, differential scanning calorimetry （DSC）, and thermogravim- etric analysis （TG）, respectively. The results showed that the conversion of double bonds increased at primary stage and then decreased with the increment of the dosage of initiators meanwhile increased with the increment of irradia- tion time. Relative cured speed increased with the dosage of initiator, irradiation intensity, and the decreasing lamp distance. |
