ADDITIVE POLY-(5-TRIMETHYLSILYLNORBORN-2-ENE) AND METHOD FOR SEPARATING GASEOUS MIXTURES BY MEMBRANE BASED ON THEREOF Russian patent published in 2007 - IPC C08F132/04 C07C7/144 B01D71/44

Abstract RU 2296773 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of novel additive poly-(5-trimethylsilylnorborn-2-ene) that can be used in different fields of industry and, in particular, in processes for separation of gases. Additive polymer no containing double bonds in the main chain, namely poly-(5-trimethylsilylnorborn-2-ene) corresponds to the following formula: , wherein n = 170-2000 (polymerization degree), value of average-weight molecular mass M_w = (2-40) x 10⁴ g/mole and polydispersity index M_w/M_N = 1.5-3.0. Proposed polymer is used in a method for membrane separation of gaseous mixtures with the super-high coefficient of gas permeability.

EFFECT: improved separating method, valuable properties of polymer.
