以丙二醇、乙二醇、乙二醇单甲醚和乙二醇二甲醚为溶剂合成了聚甲基丙烯酸2-羟乙酯网络，研究了溶剂对聚合过程相分离的影响。从转化相图，浊度测量，溶胀研究，和粘度测量的结果表明，相分离过程取决于有机溶剂的溶解度参数，在凝胶形成过程的每个阶段的瞬时单体浓度，和交联剂的反应混合物的含量。
Poly(2-hydroxyethyl methacrylate) networks were synthesized in aqueous solutions of propylene glycol, ethylene glycol, ethylene glycol monomethyl ether, or ethylene glycol dimethyl ether and the influences of solvent on phase separation during the polymerization process studied. Results from conversion-phase diagrams, turbidity measurements, swelling studies, and viscosity measurements show that the phase separation process is dependent upon the solubility parameter of the organic solvent, the instantaneous monomer concentration at each stage of the gel formation process, and the crosslinker content of the reaction mixture.
