Abstract (English):
Hydrolytic polycondensation in a water-alcohol medium 2- [(triethoxysilylpropyl)amino]pyridine in the presence of copolymers of ethylene glycol and vinyl glycidyl ether with vinyl chloride composites were obtained. Membranes based on synthesized composites doped with phosphoric acid exhibit ion-exchange activity. The proton conductivity of the membranes is 1,19-2,89 mS/cm, the activation energy of proton transfer is 15,11 kJ/mol, the ion-exchange capacity is 1,6 mg-eq/g, the water absorption is up to 60,8 %.
