Addition polyalkylnorbornenes: A promising new class of si-free membrane materials for hydrocarbons separation / A. I. Wozniak, E. V. Bermesheva, I. L. Borisov et al. // Macromolecular Rapid Communications. — 2019. — P. 1900206. [ DOI ]

Composite fibers from cellulose solutions with additives of bis (trimethylsilyl) acetylene and alkoxysilanes: Rheology, structure and properties / I. S. Makarov, L. K. Golova, L. K. Kuznetsova et al. // Fibre Chemistry (English Translation of Khimicheskie Volokna). — 2019. — Vol. 51, no. 1. — P. 26–31. Solid–state dissolution in N–methylmorpholine N–oxide was used to obtain solutions of mixtures derived from cellulose and various organosilicon additives, namely, tetraethoxysilane, vinyltriethoxysilane, and bis (trimethylsilyl)acetylene. Optical study of the phase composition and morphology of these solutions showed that they are two–phase emulsions with a rather broad size distribution of particles of the dispersed phase. The nature of the flow of the mixed systems in continuous and dynamic deformation when the rheological behavior is monotypic depends to a certain extent on the nature of the organosilicon additive. Dry wet–jet spinning was used to obtain composite fibers. The structure and morphology of these fibers were studied as well as their mechanical and thermal properties. Analysis of the x–ray patterns diffractograms of the cellulose and composite fibers showed that the introduction of organosilicon additives into the cellulose matrix leads to less structural ordering of the cellulose. The mechanical characteristics of the composite fibers show some decrease in the strength and deformation characteristics with an increase in the elastic modulus in comparison with the cellulose fibers. Heat treatment of the cellulose and composite fibers up to 1000oC revealed a significant increase in the mass of carbon residue, whose amount depends on the type of additive. [ DOI ]

Crosslinking of addition copolymers from tricyclononenes bearing (ch3)3si- and (c2h5o)3si-groups as a modification of membrane gas separation materials / D. A. Alentiev, E. S. Egorova, M. V. Bermeshev et al. // Polymer Engineering and Science. — 2019. Here, we report the synthesis and the study of gas-transport properties of crosslinked highly permeable copolymers from Si-containing norbornene derivatives. The initial high-molecular-weight copolymers were prepared via addition copolymerization of 3-trimethylsilyltricyclo[4.2.1.02,5]non-7-ene (TCNSi1) with 3-triethoxysilyltricyclo[4.2.1.02,5]non-7-ene (TCNSiOEt) in good or high yields using a Pd-catalyst. The obtained copolymers included up to 10 mol% of TCNSiOEt units bearing reactive Si–O–C-containing substituents. The crosslinking was readily realized by using simple sol–gel chemistry in the presence of Sn-catalyst. The formed crosslinked copolymers were insoluble in common organic solvents. Permeability coefficients of various gases (He, H2, O2, N2, CO2, CH4, C2H6, C3H8, n-C4H10) in these copolymers before and after crosslinking were determined and the influence of the incorporated TCNSiOEt units as well as the crosslinking on gas transport properties were established. As a result, it was found that only a small reduction of gas-permeability was observed when TNCSiOEt units were incorporated into the main chains, and the copolymers were crosslinked. At the same time, the selectivity for C4H10/CH4 pair was increased. The suggested approach has allowed obtaining crosslinked polymers from Si-containing monomers without a loss of the main membrane characteristics. POLYM. ENG.
