Hydrodynamic properties of the homologous series of the homopolymer 2deoxy2methacryla midoDglucose and the copolymers of 2deoxy2methacrylamidoDglucose with unsaturated acids in 0.2 M NaCl are studied via static and dynamic light scattering, viscometry, refractometry, and translational diffu sion. The copolymers synthesized via the freeradical copolymerization of 2deoxy2methacrylamidoD glucose with acrylic acid or methacrylic acid contain ~20 mol % acid units. At this amount of acid units, the equilibrium rigidity of copolymer chains corresponds to that of homopolymer chains. The copolymers are distinguished by the hydrodynamic characteristics of molecules. The copolymer with methacrylic acid is sim ilar to the homopolymer, whereas the copolymer with acrylic acid features substantially different parameters of relationships relating the hydrodynamic characteristics of homologs to their molecular masses.
