Silicas with Polyoxyethylene Branches for Modification of Membranes Based on Microporous Block Copolymers
نویسندگان
چکیده
We have synthesized cubic and linear polysiloxanes containing polyoxyethylene branches (ASiP-Cu) using tetraethoxysilane, glycol, copper chloride as precursors; the products are stable to self-condensation. The effect of content on chemical structure ASiP-Cu has been established. A special study was aimed at defining modifying sorption characteristics membranes based microporous, optically transparent block copolymers (OBCs). These OBCs were produced 2,4-toluene diisocyanate ethylene propylene oxides. demonstrated significantly increased capacity modified polymers. On basis microporous 1-(2-pyridylazo)-2-naphthol (PAN) analytical reagent, an test system developed. Additionally, benefit high diffusion permeability for molecules organic dyes metal ions. It shown that volume voids structural features their internal cavities contribute complex formation reaction involving PAN chloride.

BACKGROUND Because European-wide directives are restricting the non-clinical use of antibiotics as in-feed growth promotors in swine production, there is an intensive search for alternative strategies for control and prevention of losses among young pigs. With the growing knowledge of the porcine immune system and its endogenous modulation, it has been clearly established that exogenous immunom...
