摘要
以甲基丙烯酸羟乙酯、衣康酸为原料合成衣康酸甲基丙烯酸羟乙酯(HEMAIA),然后使之与环氧大豆油(ESO)进行开环反应,合成含有侧甲基和多个碳碳双键的ESO-HEMAIA。研究不同反应条件对ESO-HEMAIA合成的影响,采用红外光谱(FT-IR)和核磁共振氢谱(1H-NMR)对所合成的产物进行表征分析,同时,对纯ESO-HEMAIA与环氧大豆油丙烯酸酯(AESO)的双键转化率及涂膜性能进行研究。结果表明,ESO-HEMAIA的官能度最高可达5. 2;虽然AESO的双键转化率高于ESO-HEMAIA,但纯ESO-HEMAIA比AESO涂膜有着更好的硬度、热稳定性,吸水率可降至1. 01%。
Hydroxyethyl itaconic acid methacrylate(HEMAIA)was synthesized by using hydroxyethyl methacrylate and itaconic acid as raw materials,which was further reacted with epoxidized soybean oil(ESO)viaring-opening reaction to synthesize the ESO-HEMAIA containing two active C=C groups and side methyl groups. The effects of different reaction conditions on the synthesis of ESO-HEMAIA were studied,and the chemical structures of HEMAIA and ESO-HEMAIA were characterized by FTIR and1 H NMR. Meanwhile,the double bond conversion rate and coatings properties of pure ESO-HEMAIA and AESO were studied. The results showed that the optimal functionality of ESO-HEMAIA was up to 5. 2.Though the AESO has a higher double bond conversion rate than ESO-HEMAIA,the pure ESO-HEMAIA provided better hardness,thermal stability and reduced water absorption to1. 01% compared with AESO coatings.
