Аннотация: A chemical modification of PIM-1 polybenzodioxane (a polymer with intrinsic microporosity) is performed by reactions with the involvement of the nitrile group and using a selective quinazoline synthesis reaction. A number of benzanilide-substituted derivatives of PIM-1 are obtained based on the high-molecular-weight samples of PIM-1. The gas transport properties of the membranes based on substituted PIM-1 polymers with a degree of substitution of up to 50% are studied. It is shown that the values of the gas separation parameters for O(2)and N(2)are on the upper bound of the Robeson diagram (2008) for a sample with a degree of substitution of 50%. According to estimates, these values should be significantly above the upper bound of the Robeson diagram (2008) at a degree of substitution of 100%.
