Synthesis and Characterization of Macroporous Microbeads of Poly(styrene-co-divinylbenzene) with Residual Double Bonds

Department of Chemistry, Shandong University, Ji'nan 250100

Received Date: 3 July 1997
Revised Date: 12 January 1998

Using toluene solution of linear polystyrene as porofor, the macroporous microbeads of poly(styrene-co-divinylbenzene) were prepared by suspension polymerization. Their pore volume and pore size distributions were measured by mercury porosimetry and bead textures were observed by scanning electron microscope. The influences of porofor composition, porofor amount and DVB content upon pore volume and pore size distribution have been investigated. The presence of the residual double bonds in the microbeads was confirmed by FT Infred-red spectra. It is concluded that about 40% of the secondary double bonds were remained active after polymerization.
