Crosslinked macroporous hydrogels based on 2-hydroxyethyl methacrylate (HEMA)-[2-(methacryloyloxy)ethyl]trimethylammonium chloride (MOETACl) copolymer, HEMA-MOETACl-methacrylic acid (MA) terpolymer, and on a polyelectrolyte complex of HEMA-MA copolymer with poly(MOETACl) were prepared. All the hydrogels were prepared in the presence of fractionated sodium chloride particles. The hydrogels were characterized by the number of pores and the total volume of all pores in unit volume, the average volume and the average diameter of single pore. Morphology of the hydrogels was investigated by confocal and scanning electron microscopy. The hydrogels based on polyelectrolyte complexes were also characterized by chemical composition. Homogeneous (non-porous) hydrogels with the same composition as macroporous hydrogels were prepared and characterized by their biocompatibility.
制备了基于甲基丙烯酸2-羟乙酯（HEMA）-[2-(甲基丙烯酰氧基)乙基]三甲基氯化铵（MOETACl）共聚物、HEMA-MOETACl-甲基丙烯酸（MA）三元共聚物以及HEMA-MA共聚物与聚（MOETACl）的聚电解质复合物的交联大孔水凝胶。所有水凝胶均在分级氯化钠颗粒存在下制备。通过单位体积内的孔数和所有孔的总体积、单个孔的平均体积和平均直径对水凝胶进行表征。通过共聚焦和扫描电子显微镜研究水凝胶的形态。基于聚电解质复合物的水凝胶还通过化学成分进行表征。制备了与大孔水凝胶组成相同的均相（无孔）水凝胶，并对其生物相容性进行了表征。
