Abstract
An original method for the synthesis of monomer for the preparation of a new membrane polymer, 2,2,4,4,6,6-hexamethyl-1-oxa-2,6-disyl-4-germanocyclohexane, is proposed, which allows increasing the yield of the target substance. By polycondensation polymerization, a membrane-forming germanium-containing polycarbosiloxane was synthesized. Based on it, new highly permeable membranes with high selectivity of butane / methane were first obtained and studied. When comparing the transport properties of silicon and germanium-containing polymers, it was found that polycarbosiloxane containing germanium atoms in the main chain shows higher values of butane selectivity and permeability.
