摘要

利用60Co γ射线在室温下辐照双连续相微乳液体系以制备多孔聚合物材料

试图在控制多孔材料的微孔结构形态和减少微乳液聚合过程中的相分离方面做一些探索 .通过电导率的测量分析微乳液的结构类型

并确定微乳液的双连续相区域范围 .微乳液聚合后所得的样品的孔结构和聚合前的微乳液结构类型有关

扫描电镜和热重分析的结果表明双连续相微乳液在聚合时容易发生相分离

未必能够得到开孔结构的聚合物 .但适当控制聚合前微乳液的组成

如选择合适的水油比例、交联剂的用量和加入一些功能性单体 (如甲基丙烯酸或丙烯酸钠 )

可以有效地抑制相分离

调节所得聚合物的结构形态 .

Abstract

Porous polymeric materials could be successfully prepared by gamma radiation polymerization of BA- containing micmemulsions．The main aims of this paper are txying to control the pore structures of the polymer obtained by mlcroemulsion polymerization and to alleviate the occurrence of phase separation during the polymerization of miememulsions．The emulsifier systems

including a nonionic mixture of OP-4 and OP-10

an anionic-nonionic mixture of SAO and OP-10

a cationic-nonionie mixture of CTAB and OP-4

could be used successfully to prepare stable

transparent mieroemulsions

which have different bicontinuous phase range The resulting polymers were studied by scanning electron microscopy (SEM)．It was found that their morphology characteristics strongly depended on the composition (water content

crosslinker content

functional comonomer) of the precursor microemulsions．
