Small-angle light scattering membranes

Cylindrical structures of finite thickness were consistent with the small angle light scattering (SALS) data obtained on hydrated poly(2-hydroxyethyl methacrylate), a polymer similar to those used for reverse osmosis membranes ( ).

The samples prepared by this chlorosilane route are characterized by high degrees of molecular and compositional homogeneities, as was confirmed by the exhaustive characterization data provided by SEC, membrane osmometry, low angle laser light scattering, differential refractometry, vapor pressure osmometry, UV-SEC, and NMR. The most important feature of the method is that every step of the reaction is monitored by taking small aliquots from the reaction mixture.
