Description
Summary:[Display omitted] Dense purely methylsiloxane molecular brushes with high molecular masses were obtained by the ‘grafting to’ method. Vinyl groups of poly(vinyldimethylsiloxy)methylsiloxane were converted into (chlorodimethylsilyl)ethyl ones whose active chlorine atoms were replaced by monofunctional dimethylsiloxane oligomers having OLi terminal group to arrange side arms of the product. The molecular brushes thus prepared were characterized using physicochemical methods of analysis.
