摘要：PURPOSE:To develop a solid amine based repeatedly usable CO2 gas adsorbing porous resin having improved adsorptivity, by subjecting porous polymer particles obtained by polymerizing divinylbenzene with glycidyl methacrylate to addition reaction of a polyfunctional amine. CONSTITUTION:A CO2 adsorbing porous resin, obtained by mixing divinylbenzene (DVB) with glycidyl methacrylate (GMA) at 7:93-65:35 weight ratio, adding 60-230pts.wt., based on 100pts.wt. total of the DVB and GMA, 4-methyl-2- pentanol as a precipitant to the resultant mixture, suspension polymerizing the mixture in water to form fine primary polymer particles having <=1mum diameter, converting the primary articles into an aggregate to form a microreticular type porous polymer, subjecting the polymer to addition reaction of a polyfunctional amine, e.g. polyethyleneimine having <=10,000 molecular weight to form an amine adduct porous polymer and washing the polymer with water, hot water and methanol to remove the precipitant and residual polyfunctional amine and having improved adsorptivity.
