Free radical copolymerization is used for the synthesis of novel water-soluble copolymers of vinylphosphonic acid with 2-deoxy-2-methacrylamido-D-glucose or 4-acryloylmorpholine, with varied compositions and molecular masses, as well as for the synthesis of copolymers of vinylphosphonic acid with acrylamide. The obtained copolymers contain 6-97 mol.% of vinylphosphonic acid units, and their molecular masses vary from 5 × 10 to 310 × 10. The monomer reactivity ratios of vinylphosphonic acid and 2-deoxy-2-methacrylamido-D-glucose in copolymerization are determined for the first time, and their values are 0.04 and 9.02, correspondingly. It is demonstrated that the synthesized copolymers form luminescent mixed-ligand complexes with Eu, thenoyltrifluoroacetone, and phenanthroline. The influence of the comonomer's nature on the intensity of the luminescence of complex solutions is revealed.
自由基共聚用于合成具有不同组成和分子量的乙烯基膦酸与2-脱氧-2-甲基丙烯酰胺基-D-葡萄糖或4-丙烯酰基吗啉的新型水溶性共聚物，以及用于合成乙烯基膦酸与丙烯酰胺的共聚物。所得到的共聚物含有6-97摩尔％的乙烯基膦酸单元，其分子量在5×10至310×10之间变化。首次测定了乙烯基膦酸与2-脱氧-2-甲基丙烯酰胺基-D-葡萄糖在共聚中的单体反应比，其值分别为0.04和9.02。结果表明，合成的共聚物与铕、噻吩甲酰三氟丙酮和菲咯啉形成发光混合配体配合物。揭示了共聚单体的性质对配合物溶液发光强度的影响。
