Multiple surface structures in polyolefins formed by modification methods

New methods for the formation of multiple surface structures in polyolefins were developed both at the molecular and macromolecular levels, which produced a high local nonuniformity of surface properties. In particular, I obtained varied molecular structures at the surface as a result of consecutive heterophase fluorination and sulfonation reactions of the polymers. Nonuniform macroscopic surface structures were formed with dosed thermal and deformation treatments of prefluorinated polymeric materials with the partial destruction of the formed modified layer and the subsequent predominant sulfonation of the disclosed macroscopic regions of the initial nonfluorinated polymer. The kinetics of the multiplet structure formation were studied. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 95:1198–1208, 2005
