| Abstract: | The reactiving ratios of vinyl acetate (VAc) and divinyl benzene (DVB) werecalculated from the Q and e values. The possibility of the copolymerization of thesetwo monomers was predicted and the copolymerization was carried out by-sin pensionpolymerization technique in the presence of pore producing agent (toluene andgasoline). The relative ratio of acetoxy group and benzene ring in the copolymer weremonitored by IR measurement during the polymerization. The variation of poreproperties, such as specific surface area, porosity and average pore diameter withpolymerization time were determined The copolymers at various polymerization timewere alcoholyzed and thus the variation of the hydroxyl group content withpolymerization time was studied. |
