Synthesis and Properties of High Oil-Absorbing Resins with Long Chain by High Internal Phase Emulsions as Template

Abstract

Synthesis of porous high oil-absorbing resins by high internal phase emulsions (HIPEs) as template was described. Lauryl methacrylate (LMA), hexadecyl methacrylate (HMA), and steary methacrylate (SMA) with long-chain alkyl groups were chosen as monomers to prepare high oil-absorbing resins. Effects of different factors including initiator, crosslinker, emulsifying agent, porogen, reaction temperature, reaction time, and volume ratio of water/oil on oil-absorbing capacity were discussed. The maximum capacities of the high oil-absorbing resins prepared by LMA, HMA, and SMA were 24 g.g−1, 32 g.g−1, and 34 g.g−1 in trichloromethane, respectively. The oil-absorbing capacities of these resins remain constant after three times desorption and absorption processes.
