Аннотация:A procedure of selective bromination of poly(1-trimethylsilyl-1-propyne) using N-bromosuccinimide as the brominating agent was developed. This method allows to obtain samples with different bromine content depending on the process conditions. The obtained brominecontaining polymers have good film forming properties, satisfactory thermal and thermooxidative stability. The introduction of bromine atoms into the polymer increases the stability of the latter to aliphatic hydrocarbons C5—C12 and improves hydrophobicity. With an increase of bromine content in the polymer, the selectivity of separation of gas pairs CO2/N2, CO2/H2, and O2/N2 increases, while the level of permeability remains high.
