                 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。

                 Abstract: 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) (4SH) and prepared two thiol-ene click polymers (EUPH/4SH and EUIS/4SH),
                 respectively. The thermal properties, thermomechanical properties, thermal stability and tensile properties
                 of  EUPH/4SH and EUIS/4SH were characterized by  DSC, DMA, TGA and  universal material  testing
                 machine. The results showed that EUIS/4SH 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/4SH were attributed to the
                 unique  rigid  molecular structures of EUIS and the  high  network crosslinking density of EUIS/4SH.
                 Moreover, the cytotoxicity grade of EUIS/4SH was grade 0, demonstrating that it had potential application
                 value in biomedical materials.
