the preparation and adsorption of poly (p-hydroxystyrene) adsorbents - Production method
P> add 0.5% polyvinyl alcohol aqueous solution and several drops of methylene blue solution into a three-mouth bottle equipped with a stirrer and thermometer, raise the temperature to 45 ℃, then add a certain proportion of mixed organic solution of p-benzoyloxystyrene, divinylbenzene, porogen and benzoyl peroxide for suspension polymerization, react at 80 ℃ for 4h, react at 90 ℃ for 6h, filter, rinse with hot water, then extract with acet, the crosslinked poly (p-hydroxystyrene) adsorption resin was obtained by hydrolysis at 65 ℃ for more than 10h with 5% NaOH-methanol solution.
