article, we report the preparation and properties of the bulk supramolecular polymer gels prepared from a polybutadiene based on the amidinium‐carboxylate salt bridge, highlighting the difference from a well‐established network system based on carboxylic acid and amine. We have prepared the amidinium‐carboxylate salt bridge‐based supramolecular polymer gels from a carboxy‐terminated telechelic polybutadiene
在本文中,我们报告了由基于羧酸铵盐桥的聚丁二烯制备的大分子超分子聚合物凝胶的制备和性能,突出了与基于羧酸和胺的成熟网络系统的区别。我们从羧基端基的远螯聚丁二烯和具有N,N的线性聚am制备了基于idi盐盐桥的超分子聚合物凝胶主链中的'-二取代乙am基团。FTIR分析以及小角度X射线散射测量表明,盐桥归因于三维网络形成的胶凝作用。对于含有等摩尔量的羧基和the基的超分子凝胶,几乎没有观察到流动性,在室温下显示出约1 MPa的高G '值,在37°C下显示出T凝胶。为了进行比较,使用线性聚乙烯亚胺代替聚am制备了通过羧酸铵盐交联的超分子聚合物凝胶。羧基和仲氨基等摩尔量的凝胶显示出类似液体的流动性,GFTIR分析表明,室温下的′值约为0.01 MPa,这归因于一定量的羧基以游离形式保留而没有形成盐的事实。©2014 Wiley Periodicals,Inc.
