WebIt was demonstrated recently that the combination of urea and imide groups in hard blocks increases the mechanical properties of membranes due to physical cross-linking . At the same time, growth of soft-segment content results in the increased permeability of membranes toward CO 2 [ 18 ]. WebApr 2, 2014 · Cross-link is a bond which links one polymer chain to other. It can be ionic or covalent. Cross linking changes a liquid polymer into ‘solid’ or ‘gel’ by restricting the ability of movement. When polymer chains are linked together by cross-links, they lose some of their ability to move as individual polymer chains.
