- Аннотация: Polyurethanes based on the aminoethers of ortho-phosphoric acid and polyisocyanates of an aliphaticnature were studied as a substrate for the preparation of new polymer electrolyte. The conductivity ofpolyurethane ionomer samples obtained using the optimal amount of aliphatic polyisocyanates and afterkeeping them in a 1 M LiBF4 solution in g-butyrolactone reaches 0.62 mS cm1. It has been establishedthat the transport of positively charged ions through the polymer matrix is due to the formation ofclusters of phosphate ions and their association into the conducting channels. The introduction ofcarboxylate ions into the conducting channels by modifying the aminoethers of ortho-phosphoric acidwith phthalic anhydride leads to an increase in their size and rise in the mobility of cations. As a result,the conductivity of polyurethane gel electrolytes increased to 2.1 mS/cm.
