Gas Transport Properties of Metathesis Polynorbornene with the Substituents in the Side Chain Based on Β-(–)-Pinene

Year: 2025

Type: article

Abstract: The gas separation properties of a high-molecular-weight metathesis polymer based on nadimide containing β-(–)-pinene fragments, synthesized in the presence of the first-generation Grubbs catalyst, were studied. In particular, the permeability and diffusion coefficients for a wide range of gases were determined for the first time. This polymer is characterized by low values of gas permeability coefficients, corresponding to the gas permeability level of polyimides and cellulose acetate. At the same time, the selectivity of separation of gas pairs containing CO2 and O2/N2 pair for the polymer explored is significantly higher than that of the related unsubstituted metathesis polynorbornene.
