Abstract
PURPOSE:The reaction of a chloromethylated and crosslinked polystyrene with hydroxythiacrown is effected to produce title substance that is useful as interphase shifting catalyst or agent for capturing heavy metals, readily recovered and low toxicity. CONSTITUTION:A chloromethylated and crosslinked polystyrene is reacted with hydroxythiacrown of formula I to form said fixed crown containing the structure of formula II (P means the crosslinked polystyrene) as a part. The reaction is effected in an inert solvent as THF in the presence of a base at 0-100 deg.C. It is desirable that at first the hydroxy-thiacrown is reacted with a base as sodium hydride, then with the chloromethylated and crosslinked polystyrene. The compound of formula I is used in an excessive amount, preferably 1-10 moles of the compound of formula I per 1 gram equivalent of chlorine atom.
