Fully Crosslinked Stable Poly(methyl methacrylate-co-divinylbenzene) Microspheres by Precipitation Polymerization and Their Properties |
| 초록 |
Fully crosslinked stable poly(methyl methacrylate-co-divinylbenzene) microspheres composed of various concentrations of divinylbenzene from 5 to 75 mol.% based on methyl methacrylate monomer were prepared without a significant particle coagulation by precipitation polymerization. The number-average particle diameter is in the range of 0.74 ~ 2.2 μm and decreases with increasing concentration of divinylbenzene in monomer. The glass transition temperature was not observed for all microspheres formed from whole range of divinylbenzene concentrations. In addition, the onset of thermal degradation temperature was significantly increased from 328.7 to 377.6℃. And their yield was also increased from 73.4 to 98.6 %. Based on the DSC and TGA data, it is concluded that the polymer microspheres prepared by precipitation polymerization possess fully crosslinked structure and highly enhanced thermal stability. |
