Poly[{(BuSn)12O14(OH)6}(AMPS)2] and poly[methyl acrylate-co-{(BuSn)12O14(OH)6}(AMPS)2]: hybrid polymers cross-linked through electrostatic interactions

Abstract

A butyltin oxo-cluster, {(BuSn)₁₂O₁₄(OH)₆}²⁺, functionalized through electrostatic interactions with two 2-acrylamido-2-methyl-1-propanesulfonate anions (AMPS), has been synthesized and characterized by single crystal X-ray diffraction and multinuclear (¹H, ¹³C and ¹¹⁹Sn) NMR. Its polymerization or co-polymerization with methyl acrylate yield hybrid materials where the nanobuilding blocks are fully preserved and act as nano-fillers and cross-linking agents. According to the electrostatic nature of the cross-linking, these materials can yield gels or solutions depending on the solvent used to swell them.
