Fully crosslinked stable poly(GMA-co-divinylbenzene) microspheres composed of various concentrations of divinylbenzene from 5 to 75 mol.% relative to glycidyl methacrylate monomer are prepared by precipitation polymerization. Polymerization characteristics including yield of polymerization, particle size and uniformity, surface area, and thermal properties are investigated. The number-average particle diameter is in the range of 2 ~ 4 and increases with concentration of divinylbenzene in monomer. Furthermore, it is found that the concentration of divinylbenzene plays a significant role in determining yield, size, stability and thermal properties of the microspheres. |
