Vicinal diol-containing monomers are prepared by reacting, in aqueous solution, a monomer of formula
where R1 is H or CH3; Y is O or NH; R3 and R4 are each CH3 or C2H5; n is 2 or 3; X- is halogen-,½ SO4=, CH3SO4-, C2H3SO4- or CH3COO-;
with at least one reactive vicinal diol -forming or -containing compound selected from glycidol and the 3-halo-1,2-propane- diols. Vicinal diol-containing polymers made from these monomers can be cross-linked to form high viscosity gels.
在水溶液中,将式中 R1 为 H 或 CH3;Y 为 O 或 NH;R3 和 R4 分别为 CH3 或 C2H5;n 为 2 或 3;X- 为卤素-、½ SO4=、CH3SO4-、C2H3SO4- 或 CH3COO-,与至少一种反应性的形成或含有代二元醇的化合物反应,这些化合物选自缩水甘油和 3-卤代-1,2-丙二醇。 由这些单体制成的含代二元醇聚合物可以通过交联形成高粘度凝胶。
