END-FUNCTIONALIZED POLYMERS .1. SYNTHESIS AND CHARACTERIZATION OF PERFLUOROALKYL-TERMINATED POLYMERS VIA CHOROSILANE DERIVATIVES

Surface-active, perfluoroalkyl-terminated block copolymers were synthe sized and characterized. These heterophase block copolymers were made by terminating a variety of living anionic polymerizations with a chlo rosilane derivative containing a perfluoroalkyl group. This synthetic methodology was successfully applied to the anionic polymerization of styrene and 1,3-dienes. Perfluoroalkyl-terminated poly(olefin)s were o btained via hydrogenation of the unsaturated poly(diene) materials. Ex cellent control of the molar mass, molar mass distribution, and functi onality was verified using conventional characterization techniques su ch as gel permeation chromatography, NMR, and elemental analysis. In a ddition, time-of-flight secondary ion mass spectrometry (TOF-SIMS) was employed to characterize the absolute molar masses and molar mass dis tributions and also the extent of functionalization.
