Abstract
Poly(divinylbenzene) [poly(DVB)] derivatives having hydroxyl terminals and/or pendants were synthesized by chemical modifications (hydration and hydroxylation) of unsaturated linear poly(DVB) (I), which was prepared by the polymerization of DVB catalyzed by acetyl perchlorate. Hydroboration of both terminal and in-chain carbon–carbon double bonds in I with BH3.THF complex yielded a fully hydrated poly(DVB) II, in which hydrophilic and hydrophobic groups are placed alternately. Selective hydroboration of the vinyl endgroups in I with 9-borabicyclo[3.3.1]nonane led to an α,ω-dihydroxy-poly(DVB) (III). Reaction of I with m-chloroperbenzoic acid gave fully epoxidated poly(DVB) IV, which was subsequently hydrated to yield polymer V consisting of glycol repeat units and terminals. The physical properties and reactions (chain extension and crosslinking) of these polymers were also studied.
