摘要

Reaction of diallylamine with crosslinked terpolymer beads of glycidyl metacrylate–methyl methacrylate–ethylene glycol dimethacrylate yields corresponding polymers with diallylamino functions (2.4 mmol g⁻¹). Cis-dihydroxylation of the allyl groups with hydrogen peroxide, in presence of OsO₄ catalyst yields polymer supported amino-bis(cis-propane 2,3-diol) functions with 81.7%of conversion yields. The resulting polymer resin having vicinal cis-diol functions is a high capacity (1.77 mmol g⁻¹) boron-specific sorbent and useful for extraction of of trace boric acid (105.1 ppm) from aqueous solutions in about 20 min.
