New cyclolinear polyureas based on a crown-containing diamine – 1,10-diaza-18-crown-6 – and organic diisocyanates of different nature have been synthesized. Also have been obtained block copolymers containing elastic olygodimethylsiloxane and hard urea blocks. It has been shown that the basic characteristics of these cyclolinear systems can be tailored by varing the nature of the diamine comonomers and reagents ratio. It has been shown that these polymer compounds represent practical interest for different ion- and gas-separation membranes manufacturing, including composite membranes.
