Abstract

Polymer microspheres with functional groups are attractive for a wide number of applications, including supporting phases for separation science, biomedical devices, casting additives and controlled release reservoirs. In this paper, Poly(divinylbenzene-co-4-vinylpyridine)(Ploy(DVB-co-4-Vpy)) microspheres with functional pyridyl was prepared by distillation-precipitation polymerization and precipitation polymerization separately when 2,2'-Azobisisobutyronitrile (AIBN) as initiator in net acetonitrile. The feature of microspheres was characterized by TEM while the loading capacity of nitrogen on microspheres' surface and the hydrophilicity were measured by back titration and contact angle measurement. Under the same crosslinking degree, the microspheres prepared by distillation-precipitation polymerization had better feature, smoother surface, more functional groups and better hydrophilicity but lower yields than the ones prepared by precipitation polymerization.
