MORPHOLOGY OF PERFLUOROALKYLACRYLATE STEARYL METHACRYLATE POLYMERS AND THEIR EFFECT ON WATER/OIL REPELLENCY/

The small-angle X-ray scattering technique was applied to study the mo rphology of a series of water-repellent terpolymers polymerized from a fluoro-component, a hydrocarbon-component and a crosslinking agent. T he intraparticle homogeneity of the terpolymers was semiquantitatively determined from the small-angle X-ray spectra using a proposed struct ural model. The X-ray results were correlated to the water repellency test data using the AATCC test method 22-1989. The consistency of the polymerization reaction process as a function of the weight ratio of t he fluoro-components is discussed. (C) 1997 John Wiley & Sons, Inc.
