| 摘 要： | 粒径在微米级、粒度分布窄的高分子微球具有十分广泛的应用。但是由于这样规格的微球正是在一般的悬浮聚合和乳液聚合的合成范围之外,而采用二步聚合法和种子聚合法则不是需要使用特殊的反应装置,就是合成步聚十分繁复,因此至今对于这样规格高分子微球的报道不多。

| Abstract: | Crosslinked functional microspheres with Carboxylic group have been synthesized by the method of Phaseseparated polymerization from monomers of methacrylic acid and other vinyl-type monomers. The effects of reaction condition such as comonomer, crosslinking agent, initiator and polymerization temperature, as well as polymerization time on the morphological structure of microspheres formed have been studied. The functional polymeric microspheres with good spherical form, diameter near 5 micrometers, narrow dispersion in diameter and contained carboxylic group can be synthesized stably. |
