Orientational ordering of polymer chains near the surface and asymmetry of the statistical segment of macromolecules

The parameter of the orientational order of polymer chain fragments near the substrate (film) surface in relation to the degree of asymmetry of the statistical segment of the macromolecule was discussed in terms of the model of adsorption of rigid cylinders on the substrate surface. The theoretical parameters of the orientational order were analyzed and compared with the experimental data for films of polysaccharides, sulfated phenyl-containing polymers, and polytrimethylsilylpropynes.
