Poly(trifluoroethylacrylatemethylsiloxane) and Polydecylmethylsiloxane Copolymer: A New Polymer for Membrane Applications

A series of poly(trifluoroethylacrylatemethylsiloxane) (F3) and polydecylmethylsiloxane (C10) copolymers featuring different ratios of the side groups were synthesized for the first time. A significant change in the sorption of the components of the ABE-fermentation mixture was demonstrated when the ratio of C10 and F3 in the membrane material changed. It was established that the copolymer with the C10/F3 ratio of 1:1 exhibits the maximum value of n-butanol sorption. At the same time, the total flow through the membrane doubles in comparison with C10 and it is possible to stabilize the flow by 15% after prolonged contact with the real ABE mixture.
