Supramolecular polymer gels formed from carboxy-terminated telechelic polybutadiene and polyamidine through amidinium-carboxylate salt bridge

Abstract: In this 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 and a linear polyamidine having N,N′‐di‐substituted acetamidine group in the main chain.

“…In classical acid‐base reaction, the hydrogen bonds with proton transfer, which are termed as ionic hydrogen bonds, are usually formed between organic cations and anions . Recently, this type of reversible noncovalent interaction has been widely used to construct supramolecular polymers, due to its high stability and facile accessibility . The polymers based on ionic hydrogen bonding are also a type of ionomers because of the formation of ion pairs and have attracted considerable attention owing to their thermo‐reversible nature .…”

“…69,70 Recently, this type of reversible noncovalent interaction has been widely used to construct supramolecular polymers, due to its high stability and facile accessibility. [71][72][73][74][75][76][77][78] The polymers based on ionic hydrogen bonding are also a type of ionomers because of the formation of ion pairs and have attracted considerable attention owing to their thermo-reversible nature. [73][74][75][76] Endo and coworkers 75 reported the preparation of supramolecular polymer gels by mixing the ionomers of a carboxy-terminated telechelic PB and a linear polyamidine with N, N 0 -di-substituted acetamidine group in the main chain.…”

“…[29][30][31][32] Besides, chemicals with the acid and basic groups are abundant in nature and commercially available, enabling facile construction of supramolecular systems with versatile functions. Based on ionic hydrogen bonding, polymer gels [33][34][35][36] and block copolymers 37 with thermally responsive mechanical behavior have been demonstrated. Thus, it would be useful to incorporate thermoreversible ionic hydrogen bonds as alternative crosslinks into rubbers to achieve the reprocessing and recycling of crosslinked rubbers at elevated temperatures.…”

“…Supramolecular network polymers, which are the supramolecular analogue of covalently crosslinked network polymers, consist of individual polymer blocks crosslinked by noncovalent interactions, hence being defined as physical gels . A number of supramolecular network polymers have been designed and synthesized to date . Most of them are prepared from polymer chains that have randomly arrayed, noncovalent bonding units .…”
