We report a new series of supramolecular polymeric networks based on the isophthalic acid-pyridine (IPA-Py) H-bonding motif. The IPA units were attached as end-groups to telechelic poly(ethylene--butylene) to create a tetrafunctional macromonomer, which was cross-linked by the addition of various bispyridines. Some of the supramolecular polymer networks thus made display surprisingly good mechanical characteristics. We show that their structure and properties are strongly influenced by the nature of the bispyridine motif and by the fact that some of the IPA-Py motifs aggregate into particularly well-defined hard phases.
我们报道了一系列基于间苯二甲酸-吡啶（IPA-Py）氢键基序的新型超分子聚合物网络。IPA单元作为端基连接到遥爪聚（乙烯-丁烯）上，以制备一种四官能大分子单体，该大分子单体通过添加各种双吡啶进行交联。由此制备的一些超分子聚合物网络表现出令人惊讶的良好机械性能。我们表明，它们的结构和性能受到双吡啶基序的性质以及一些IPA-Py基序聚集成特别明确的硬相这一事实的强烈影响。
