摘要： 研究了枞酸烯丙酯（AA）和异海松酸烯丙酯（AI）发生UV光固化反应的区别。采用红外光谱法表征双键转化率，两者均随引发剂用量的增加先变大后减小；均随光照时间的增加呈先增大后趋于平缓的趋势，但 200 s 前，AA的UV固化产物双键转化率高；同等光照强度条件下AA的双键转化率高于AI。在同等固化条件下AA的表干时间比AI短，对应的相对固化速率快。以2-羟基-2-甲基苯丙酮（Darocure-1173）为光引发剂，用量为原料质量的 6%，光照时间 200 s，光照距离 4.5 cm，光照强度100%，在此条件下，AA和AI固化产物的数均相对分子质量分别为4 176和9 407，数均聚合度分别为12和28，两者的UV固化产物均有光滑透明的外观，均具有较好的附着力、耐冲击强度及柔韧性，均通过了耐酸、耐碱、耐盐及耐水性测定，AA和AI的硬度分别为H和HB。

Abstract: The UV curing reaction of the difference between allyl abietate(AA) and allyl isopimarate(AI) was studied. The conversion rate of the vinyl double bond was characterized and detected by FT-IR analysis. Results showed that conversion of double bonds are firstly increased then decreased with the increases of the dosage of initiators. Conversion of double bonds firstly increased and then leveling off with the increases of the illumination time, and AA is higher before the 200 s. AA is higher then AI under the same illumination intensity. Surface drying time of AA is shorter than AI, and relative curing speed become faster at the same conditions. Under the conditions of 2-hydroxy-2-methylpropiophenone(Darocure-1173)as photo initiator and dosage 6%,illumination time 200 s,illumination distance 4.5 cm and illumination intensity 100%,number average molecular weight of cure products of AA and AI are 4 176 and 9 407 with polymerisation degrees of 12 and 28, respectively. The obtained UV cured coating all have smooth and transparent appearance. It represented some superior properties in flexibility, mechanical impact strength, adhesive power, hardness, acid resistance, alkali resistance, salt resistance, water resistance, etc.. The hardness of AA and AI cured products are H and HB, respectively.

Key words: allyl abietate, allyl isopimarate, UV curing, property
