Synthesis and swelling of phosphonic-acrylic Organogels

Organogelling systems with monomers carrying ionic groups such as carboxylic acid and specially sulfonated groups exhibit enhancement in organogelation literature. Polymericalcogels based on acrylic acid and sodium styrene sulfonate using poly ethylene glycol di acrylate and ammoniumpersulfate have noticeable absorbencies in different alcohol mediums such as methanol, ethanol, propanol and etc [1]. Among copolymers of vinyl phosphonic acid (VPA), only afew comonomers such as N-iso propyl acrylamide (NIPAAm) [2], acrylamide (AM) [3] have been copolymerized with VPAand behaved as hydrogels. To the best of our knowledge, no reports have been published on acrylic organogels based onVPA in the previous literature. Herein, for this purpose, wesynthesized organogels based on VPA with applying an ionic acrylic comonomer (AMPS) and a nonionic one (AM).
