摘要
以丁香酚(EU)、邻苯二甲酰氯(PH-Cl)和间苯二甲酰氯(IS-Cl)为原料,制备了邻苯二甲酸双(4-烯丙基-2-甲氧基苯基)酯(EUPH)和间苯二甲酸双(4-烯丙基-2-甲氧基苯基)酯(EUIS);然后,EUPH和EUIS分别与四(3-巯基丙酸)季戊四醇酯(4SH)进行点击化学反应,制备了2种巯基-烯点击化学聚合物(EUPH/4SH和EUIS/4SH)。通过DSC、DMA、TGA和万能材料试验机对聚合物热性能、热机械性能、热稳定性能和拉伸性能进行了测试。结果表明,EUIS/4SH表现出更优的综合性能,玻璃化转变温度为65.4℃,拉伸强度和拉伸模量分别为(61.4±5.4)MPa和(1.4±0.1)GPa,这归因于EUIS独特的刚性分子结构和EUIS/4SH高的网络交联密度。此外,EUIS/4SH的细胞毒性等级为0级,表明其在生物医药材料中具有潜在应用价值。
Two allyl compounds,bis(4-allyl-2-methoxyphenyl)phthalate(EUPH)and bis(4-allyl-2-methoxyphenyl)isophthalate(EUIS)were prepared from eugenol(EU),o-phthaloyl dichloride(PH-Cl)and m-phthaloyl dichloride(IS-Cl).Then,compounds EUPH and EUIS reacted with pentaerythritol tetrakis(mercaptopropionate)(4 SH)and prepared two thiol-ene click polymers(EUPH/4 SH and EUIS/4 SH),respectively.The thermal properties,thermomechanical properties,thermal stability and tensile properties of EUPH/4 SH and EUIS/4 SH were characterized by DSC,DMA,TGA and universal material testing machine.The results showed that EUIS/4 SH exhibited better comprehensive properties with a glass transition temperature of 65.4℃,and the tensile strength and tensile modulus were(61.4±5.4)MPa and(1.4±0.1)GPa,respectively.These excellent comprehensive properties of EUIS/4 SH were attributed to the unique rigid molecular structures of EUIS and the high network crosslinking density of EUIS/4 SH.Moreover,the cytotoxicity grade of EUIS/4 SH was grade 0,demonstrating that it had potential application value in biomedical materials.
