【摘要】 分别阐述了良和非良混合溶剂，及非良与非良混合溶剂的致孔作用。在良／非良混合溶剂存在下通过调节两种溶剂的比例，可控制共聚体的孔径和孔容的大小，只要交联度合适，可制得比表面积较大的共聚体；在非良／非良混合溶剂存在下，可通过调节两种溶剂的比例，控制其适当的混合溶度参数，所得共聚体的比表面积也大。更多还原

【Abstract】 This paper expounded the influences of mixed solvents which consisted of poor and good solvents or two kinds of poor ones with different polarity in the copolymerization. The size of pore diameter and porosity of the copolymers can be controled by changing the ratio of good solvent to poor one. The copolymer with large surface area can be obtained by selecting a suitable degree of crosslinkage in the copolymerization carried out in the presence of poor and good solvents. And the copolymers with big surface area can be obtained by regulating the ratio of two kinds of poor solvents.更多还原
