One-Step Suspension Preparation Method for Porous Crosslinked Acrylic Acid Resin
Abstract:
A series of porous crosslinked acrylic acid copolymer beads was prepared directly by suspension polymerization of acrylic acid in the presence of 1,2-dichloroethane, toluene or heptane as the inert diluents and divinylbenzene and triallyl isocyanurate as crosslinking agents. A 45% aqueous CaCl2 solution containing 0.2% hydroxyethyl cellulose was used as the water phase. The copoly merization gave a yield more than 90% and copolymers withion-exchange capacity of 12 mmol/g were obtained. The effects of synthesis conditions,including the ratio of monomer to diluent, reaction temperture, on the resin properties were examined.
