碩士 === 中原大學 === 化學工程研究所 === 82 === Styrene was polymerized by dispersion copolymerization in
ethanol with polyvinylpyrrolidone(PVP) as stabilizer,and 2,2'-
azobisisobutyronitrile (AIBN) as initiator. The prepared mono-
disperse polystyrene particles with diameters in the range of
1-5 mm were used as the seeds in the second step of polymeri-
zation. These particles were swellen in the solution of
methacrylate as the monomer, ethylene dimethacrylate as the
crosslinking agent and toluene as the solvent diluent. After
swelling,these particles were polymerized, then were extracted
with solvent in a Soxhlet apparatus to remove diluent and
linear polystyrene. Monodisperse porous copolymer particles of
BMA-co-EDMA and MMA-co-EDMA copolymer particles were obtained.
From the exprimental datas, the following results were obtained
that the specific surface area and pore volume of the MMA-co-
EDMA particles are higher than those of BMA-co-EDMA
particles after extraction by toluene at the same reaction
condictions . The influence of diluent, toluene, the specific
surface area and pore volume of the copolymer particles was
investigated. When the concentraction of the porogenic solvent
toluene was 4.0 - 4.5 vol% in the organic phase, the specific
surface area and pore volume was higher for the copolymer
particles obtained.
