Suspension polymerization technique was used to synthesize porous polystyrene polymer cross-linked with divinylbenzene. The effects of various synthesis parameters (amount of initiator, cross-linker and diluent, type of diluent and agitation speed) were evaluated for average particle size, particle size distribution and surface morphology. The results analyzed by SEM, TEM, EDX, FTIR and sieving showed that average particle size decreases with increasing initiator amount. Optimum uniformity was obtained at low initiator amount and high cross-linker amount. The results also showed that type of diluent does not affect average particle size, while particle distribution and surface morphology were affected by agitation speed.

采用悬浮聚合技术合成了与二乙烯基苯交联的多孔聚苯乙烯聚合物。对于平均粒度，粒度分布和表面形态，评估了各种合成参数（引发剂，交联剂和稀释剂的量，稀释剂的类型和搅拌速度）的影响。通过SEM，TEM，EDX，FTIR和筛分分析的结果表明，平均粒径随着引发剂数量的增加而减小。在低引发剂用量和高交联剂用量下可获得最佳的均匀性。结果还表明，稀释剂的类型不影响平均粒径，而颗粒分布和表面形态则受搅拌速度的影响。
