N2 - Various acrylic polymers in which an aspartic acid fragment with different end groups (the first-generation dendron) is attached to the main chain either via the amide group or the 4-aminobenzoic acid residue are studied. The synthesis of monomers and polymers with the asymmetric substitution of the aspartic fragment, in which a long hexadecyl group is situated only at the -carboxyl group, is described. The molecular, optical, electrooptical, and conformational properties of the polymer containing the long hexadecyl group at the -carboxyl bond and the hydrolyzed -ester bond in the aspartic acid fragment are examined in detail. In the range M = (23–508) 103, the Mark–Kuhn–Houwink equations [] ~ M 0.53 and D ~ M–0.53 are obtained for the intrinsic viscosity and diffusion of the polymers under study in octyl alcohol. The length of the statistical Kuhn segment (120 Å), the hydrodynamic diameter of a chain (50 Å), the shear optical coefficient, and the anisotropies of the segment and monomer unit are determined.
