    Synthesis and Degradation of Photopolymerisable Crosslinked Polyanhydride

      摘要
    • 摘要: 采用甲基丙烯酸酐(或甲基丙烯酰氯)与无毒二元酸反应合成了混合酸酐:甲基丙烯酸酐化癸二酸(MSA)和甲基丙烯酸酐化的1,6-二(对羧基苯氧基)己烷(MCPH)。并用1H-NMR、IR表征其结构,结果表明:直接酸酐法制得的MSA,酰氯法制得的MCPH符合聚酸酐单体的结构特征。MSA和MCPH可以在紫外光照射下生成高度交联的聚酸酐网络,通过改变MSA与MCPH的共聚比例,可以将该网络的降解时间控制在4～70d之间。

       

      Abstract: Dimethacrylic sebacic anhydride (MSA) and dimethacrylic 1,6-bis(p-carboxyphenoxy)hexane (MCPH) were synthesized by methacrylic anhydride (or methacryloyl chloride) and nontoxic diacids, and their structures were charactered by IR and ()~1H-NMR. The results show that MSA directly synthesized by anhydride and MCPH synthesized by chloride are in accordance with the strucutres of polyanhydride monomers. These multifunctional monomers are photopolymerized using ultraviolet light to produce highly crosslinked polyanhydride networks. By copolymerizing varying amounts of MSA and MCPH, the degradation rate of the network is controlled from 4 d to 70 d.
