[1] Synthesis and co2 sorption in poly(1-trimethylsilyl-1-propyne) and polyvinyltrimethylsilane containing ethylene oxide groups and n-butylimidazol-based “ionic liquids” groups / Y. Kiryukhina, V. Khotimskiy, V. Tepliakov et al. // Desalination and Water Treatment. — 2011. — no. 35. — P. 255–262. There have been developed methods of chemical modifi cation of high permeable glassy polisilicon hydrocarbons poly(1-trimethylsilyl-1-propyne) [PTMSP] and polyvinyltrimethylsilane [PVTMS] for introducing into polymer structure of ethylene oxide groups and “ionic liquid-like” groups which are known as a group possessing strong CO2 affi nity. In addition low molecular compounds having structures close to chemically modifi ed polymers have been synthesized in order to create mechanical blends with polymers. Sorption properties of modifi ed polymers and mechanical blends were studied in order to establish infl uence of nature and quantity of introduced functional groups and also method of introducing of functional groups in PTMSP and PVTMS (chemical modifi cation or preparation of mechanical blends) on ability of reversible interaction with CO2. It was established that it is possible to surpass level of CO2 sorption that is typical for initial PTMSP and PVTMS by introducing groups specifi c to CO2, and, moreover, the level of sorption in such materials essentially depends on method of introducing of functional moieties.
