<正> A novel polymer-bound 1

2-diol

3-polystyrylsulfonyl-1

2-propanediol （6） had been prepared by the reaction of sodium polystyrylsulfinate with allyl bromide

followed by oxidation and. hydrolysis or directly with 3-chloro-1

2-propanediol in the presence of a phase transfer catalyst

n-tetrabutylammonium iodide. The capacity of resin 6 for terephthaidehyde reached 1.43 mmol/g. The aldehydic groups attached to polymer 6 reacted with hydroxylamine hydrochloride or reduced by sodium borohydride giving p-formylbenzaldoxime （yield: 89%）and p-formyl-benzalcohol （yield: 734%）

respectively. The high yields of these polymer-supported reactions showed that the polymer 6 possessed the effective isolation of its reactive sites.
