Formation of a physical crosslinked structure in polydimethylsiloxanes modified with long-chain hydrocarbon substituents with polar fragments

The dependence of rheological properties (viscosity and dynamic moduli G ′ and G ″) and time for formation of a physical network for polydimethylsiloxanes bearing ester and amide groups in aliphatic substituents at silicon atoms on the concentration of modifying units, the heating temperature, and the time of curing at elevated temperatures is studied.
