The focus of this work is on the nature of self-healing of ionically modified rubbers obtained by reaction of brominated poly(isobutylene-co-isoprene) rubber (BIIR) with various alkyl imidazoles such as 1-methylimidazole , 1-Bu imidazole , 1-hexyl imidazole , 1-nonyl imidazole and 1-(6-chloro hexyl)-1H-imidazole . Based on stress-strain and temperature dependent DMA measurements, a structural influence of the introduced ionic imidazolium moieties on the formation of ionic clusters and, as a consequence on the mech. strength and self-healing behavior of the samples could be evidenced. These results are fully supported by a mol.-level assessment of the network structure (crosslink and constraint d.) and the dynamics of the ionic clusters using an advanced proton low-field NMR technique. The results show distinct correlations between the macroscopic behavior and mol. chain dynamics of the modified rubbers. In particular, it is shown that the optimization of material properties with regard to mech. and self-healing behavior is limited by opposing tendencies. Samples with reduced chain dynamics exhibit superior mech. behavior but lack on self-healing behavior. In spite of these limitations, the overall performance of some of our samples including self-healing behavior exceeds distinctly that of other self-healing rubbers described in the literature so far. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Reference of 6294-17-3).
1-Bromo-6-chlorohexane (cas: 6294-17-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Reference of 6294-17-3
