摘要
采用分散聚合法制得了聚 (甲基丙烯酸甲酯 -甲基丙烯酸 )共聚物微球 .进而采用磁流体存在下的分散聚合法制得了磁性聚合物微球 .分别研究了共聚单体——甲基丙烯酸的用量对微球表面羧基含量、直径与直径分布的影响及磁流体用量对微球磁响应性、直径与直径分布的影响 .
The polymer microspheres of P(MMA-MAA) were synthesized by dispersion polymerization.Then the magnetic polymer microspheres were prepared by the dispersion polymerization with ferrofluid.The effects of the concentration of the comonomer,i.e.methacrylic acid,and the amount of ferrofluid on the surface carboxyl group content,the magnetic property,size and size distribution of the polymer microspherss were investigated respectively.
