End-functionalized polymers. 1. Synthesis and characterization of perfluoroalkyl-terminated polymers via chlorosilane derivatives

摘要: Surface-active, perfluoroalkyl-terminated block copolymers were synthesized and characterized. These heterophase made by terminating a variety of living anionic polymerizations with chlorosilane derivative containing perfluoroalkyl group. This synthetic methodology was successfully applied to the polymerization styrene 1,3-dienes. Perfluoroalkyl-terminated poly(olefin)s obtained via hydrogenation unsaturated poly(diene) materials. Excellent control molar mass, mass distribution, functionality verified using conventional characterization techniques such as gel permeation chromatography, NMR, elemental analysis. In addition, time-of-flight secondary ion spectrometry (TOF-SIMS) employed characterize absolute masses distributions also extent functionalization.
