  聚异丁烯-共-异戊二烯的溴化咪唑鎓衍生物：一类新的弹性体离聚物

  摘要：

  新的溴化咪唑鎓离聚物是通过卤化取代溴化聚异丁烯-异戊二烯（BIIR）和各种基于咪唑的亲核试剂而制备的。丁基咪唑（BuIm）通过BIIR中的烯丙基卤化物官能团进行N-烷基化可稳定地提供高产率的溴化咪唑鎓官能团。通过稀溶液粘度和固态流变学对所得可热成型离聚物的表征显示了离子对聚集在一系列离聚物组成范围内对材料性能的影响。通过BiIR与1,1'（1,4-丁二基）双（咪唑）和咪唑的无溶剂反应，扩大了BuIm烷基化的知识以生产热固性离聚物衍生物，其物理性质既来自共价网络又来自于离子对聚集体。

  Amine Substitution Reactions of Brominated Poly(isobutylene-co-isoprene):  New Chemical Modification and Cure Chemistry

  摘要：

  Nucleophilic substitution reactions of brominated poly(isobutylene-co-isoprene) (BIIR) with amines are characterized through studies of a model compound, brominated 2,2,4,8,8-pentamethyl-4-nonene (BPMN), and analysis of BIIR cure rheology. Nucleophilic amines do not accelerate HBr elimination from the allylic bromide within BIIR but readily engage in N-alkylation reactions with this functional group. N-Alkylation and accompanying proton-transfer reactions are shown to be reversible, and the distribution of allylic bromide, ammonium bromide salts, and their corresponding amines is dictated by equilibrium thermodynamics. N,N-Dimethyloctylamine and N-methyloctadecylamine undergo a single N-alkylation reaction with BPMN, while octylamine forms bis-N-alkylation products that can be used to generate stable cross-linked BUR networks.

  A new class of ionomers is described wherein ion‐pairs bear reactive functionality, thereby facilitating further chemical modification. Halide displacement from brominated poly(isobutylene‐co‐isoprene) by 1‐vinylimidazole is used to prepare ionomer derivatives that can be crosslinked by radical oligiomerization of pendant vinyl groups. The resulting thermosets contain a labile network of imidazolium

  描述了一种新型的离聚物，其中离子对具有反应性功能，从而促进了进一步的化学修饰。1-乙烯基咪唑从溴化聚（异丁烯-异戊二烯）中取代卤化物可用于制备离聚物衍生物，这些衍生物可通过侧基乙烯基的自由基低聚反应进行交联。由此产生的热固性材料包含一个不稳定的溴化咪唑鎓离子对聚集体网络以及一个稳定的共价网络。由于其混合的离子/共价组合物，这些热固性弹性体提供了流变，拉伸和应力松弛特性的独特组合，而常规的共价或离子网络无法实现这些特性。©2013 Wiley Periodicals，Inc. J. Polym。科学，A部分：Polym。化学 2013，51，2438–2444
