| Opis: | The study of an electrochemical synthesis of polymethylsilane from trifunctional trichloro-
methylsilane monomers identified a single polymerization pathway involving reduction of the
monomer to silyl anions and their addition to the growing polymer. The sizes of the synthesized
macromolecules, measured with dynamic light scattering, are much larger than the theoretical
size estimated for an ideal dendrimer. The reason for this, found by NMR analysis, is in a large
number of branching irregularities (defects) contained in the molecular structure, which can be
described as a hyperbranched dendritic polymer. Theoretical estimates of sizes for an ideal
dendrimer were corrected assuming a branching defect is a cavity with the volume of one
monomer. Appropriateness of the theoretical and experimental models was confirmed with a
good quantitative agreement between the experimental densities and the theoretically calculated
values. |
