MOLECULAR CHARACTERISTICS OF POLY(METHACRYLAMIDO D-GLUCOSE)

The fractions of poly(methacrylamido D-glucose) with molecular weights 7< M . 10(-4)< 550 have been studied in water by the methods of molec ular hydrodynamics. Kuhn-Mark-Houwink equations were obtained. The hyd rodynamic invariant and the sedimentation parameter were also calculat ed. The equilibrium rigidity and the hydrodynamic diameter of molecule s modeling macromolecules in solution were evaluated on the basis of t he theory of the wormlike necklace model with the effects of excluded volume taken into account at different values of the excluded-volume p arameter. The effect of fraction polydispersity on the quantitative va lues of exponents in the equations of the Kuhn-Mark-Houwink type and t he Kuhn segment length is discussed.
