| 摘 要： | 分别以丙烯酸羟乙酯（HEA）、季戊四醇三丙烯酸酯PETA、苯酐（PA）和环氧大豆油（ESO）为原料制备了经丙烯酸酯改性的UV大豆油树脂HEAPA-ESO和PETA-ESO；FFIR和^1HNMR分析确认了目标树脂的结构；综合考察了反应时间、催化剂以及温度对PA和ESO环氧基转化率的影响，最佳工艺条件为：对于HEAPA—ESO，以TPP为催化剂、HEA和PA（1．05：1）在100℃下反应2h，再升温至120℃，然后加入环氧大豆后继续反应5h～6h；对于PETAPA—ESO，以TPP为催化剂、PETA和PA（1．08：1）在110℃下反应2h，再降温至100℃，然后加入环氧大豆后继续反应5h～6h。TPP用量为1．4％，阻聚剂对甲氧基酚（MEHQ）用量为0．15％。

| Abstract: | UV-curable resins of HEAPA-ESO and PETA-ESO were prepared via reaction of 2-hydroxyethylacry- late （HEA） or pentaerythritol triaerylate （PETA） with phthalic anhydride （PA） and subsequent reaction with ep- oxidized soybean oil （ESO）. Their structures were confirmed by FFIR and 1H NMR. The effect of reaction time, catalyst and temperature on conversion of PA and epoxy groups of ESO was also evaluated. The optimized reaction conditions are listed as follows ：for HEAPA-ESO,first HEA was reacted with PA （ 1.05：1 ） under 100℃ for 2h ,af- ter that ESO was added and the mixture was reacted for another 5h -6h under 120℃ ;For PETAPA-ESO, PETA was first reacted with PA （ 1.08 ： 1 ） under 110℃ for 2h, and then the system was cooled to 100℃ and ESO was added to reacted with the mixture for another 5h - 6h. 1.4% TPP was used as catalyst and 0. 15% MEHQ as inhibitor. |
