Ethylenediaminetetraacetic Acid → 2-Propenoic acid, butyl ester, polymer with diethenylbenzene and ethenylbenzene

Participants

Reaction Steps

65 g styrene, 35 g butyl acrylate, 0.6 g divinylbenzene, 4.5 g disproportionated sodium rosinate, 0.2 g sodium alkylaryl sulfonate, and 200 g water deionized by ion exchange resins are mixed and placed in a polymerization vessel. To the resulting mixture are added 0.1 g p-menthane hydroperoxide, 0.05 g ferrous sulfate, 0.15 g sodium formaldehyde sulfoxylate, 0.07 g sodium salt of EDTA, 0.3 g t-dodecylmercaptan, and 0.5 g sodium phosphate followed by emulsion polymerization at 5° C. for 15 hours to give a styrene-butyl acrylate-divinylbenzene copolymer. Gel content of the resulting crosslinked polymer is 81%.
