Super-absorbent fiber has the property of absorbing moisture up to several thousand times its original weight, undergoing significant expansion, and eventually becoming a gel. The hydrophilic super-absorbent fiber is usually blended with hydrophobic

High-resolution solid-state 13C-NMR has been used to study the phase separation and molecular motion in two series of polyurethane foams. These two series differ by one possessing the additive of lithium chloride, LiCl. NMR relaxation times can map t

In a previous article,1 we reported on the interaction of cellulose with NH3/NH4SCN by using solid state CP / MAS 13C-NMR, wide-angle X-ray and other techniques. It appears that during an imposed temperature cycling sequence, specific cellulosic inte

It has been shown that incorporation of masked isocyanates in the MY720/DDS epoxy significantly reduces the equilibrium moisture absorption by blocking of residual functional groups ( oxirane group) by the isocyanates released in the deblocking react
