•New polar polymeric stationary phases for gas chromatography are prepared.•Simple procedure for evaluation of optimal kinetic performance limits in gas chromatography is suggested.•Effect of monomer structure on kinetic performance of capillary column with polymeric stationary phase is confirmed. Open capillary columns with polymeric stationary phases based on poly(oligoethyleneglycoldiacrylate) were prepared and tested on their kinetic performance. Stationary phases prepared with low molar mass monomers were inferior to stationary phases based on high molar mass monomers. Structure of these stationary phases appeared to be favorable for solute diffusion in the stationary phase. These columns were also characterized by improved kinetic performance limit. Stationary phase based on poly(ethylenglycol) and prepared according to the traditional procedure, demonstrated average kinetic performance. Optimal kinetic performance limit curves characterizing the prepared stationary phases were evaluated in this work using new simple procedure based on extraction of optimal values from the corresponding matrix. This technique makes it possible to evaluate optimal kinetic performance limit curves without any additional simplifications and cumbersome calculations.
