Hydrodynamic and conformational properties of poly(acrylate) molecules with side dendrons based on L-aspartic acid

Maxwell and Kerr effects in solutions of macromolecules with dendrons in side groups

“…The samples under study are characterized by high molecular masses and high masses of statistical segments [9].…”

“…The values of M A were taken from [9]. To determine the segment asymmetry parameter (L 2 − L 1 ) s , the expression (5.24) from [10] and the results of conformational investigations from [9] (Table 3) were used.…”

“…The values of M A were taken from [9]. To determine the segment asymmetry parameter (L 2 − L 1 ) s , the expression (5.24) from [10] and the results of conformational investigations from [9] (Table 3) were used. An analysis of the hydrodynamic data within the framework of wormlike and generalized [14] models shows that the axial ratio of segment A/d for P3-2 is considerably smaller than that for P3-1 both in bromoform and the acidic solvent.…”

“…The third term in (5) is the macroform effect expressed as The specific property of the macroform effect is its dependence on the molecular mass of the polymer. The value of the Flory coefficient Φ in (8) equal to 1.5×10 23 was found from the molecular characteristics of highest molecular mass fractions [9].…”

“…Systematic investigations of linear polyacrylates with side dendrons based on L-aspargic acid have been performed in [4,5,6,7,8,9]. A lack in optically anisotropic groups was responsible for quite low optical anisotropy of these polymers.…”
