Mo. Hunt et al., END-FUNCTIONALIZED POLYMERS .1. SYNTHESIS AND CHARACTERIZATION OF PERFLUOROALKYL-TERMINATED POLYMERS VIA CHOROSILANE DERIVATIVES, Macromolecules, 26(18), 1993, pp. 4854-4859
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.
