氢化松香与HEMA酯化物自聚与共聚研究

Study on the homopolymerization and copolymerization of the ester made of hydrogenated rosin and 2-hydroxyethyl methacrylate

用氢化松香(HR)与甲基丙烯酸-2-羟乙酯(HEMA)进行酯化反应,得到了酯化物(HRH),然后对其进行了在甲苯中的自由基自聚反应、以及与甲基丙烯酸甲酯(MMA)或与苯乙烯(St)的共聚反应,制备了自聚物和共聚物,用IR和核磁共振氢谱(1HNMR)对产物进行了表征,用综合热分析仪表征了产物的热稳定性和玻璃化转变温度。结果表明:成功合成了HRH自聚物(PolyHRH)、以及共聚物[Poly(HRH-co-St)和Poly(HRH-co-MMA)]。产物的热稳定性顺序为:HRH>PolyHRH>Poly(HRH-co-St)>Poly(HRH-co-MMA)。

The hydrogenated rosin and the 2-hydroxyethyl methaerylate（HEMA） were reacted to obtain the ester（HRH）. Radical homopolymerization of HRH and copolymerization with methyl methacrylate（MMA） or styrene（St） in solution had been researched, and the homopolymer（polyHRH） and the copolymers poly （ HRH-co-MMA）, poly （HRH-co-St） were characterized by IR, TG-DSC and nuclear magnetic resonance （ ^1HNMR）. The results showed that polyHRH, poly （ HRH-co-MMA ）, puly （HRH-co-St） had been synthesized successfully, and the order of thermal stability was HRH 〉 polyHRH 〉 poly （HRH-co-St） 〉 poly （HRH-co-MMA）.
