Abstract

POSS-functionalized polyisobutylenes (PIBs) were synthesized by carbocationic polymerization using an epoxy-POSS/TiCl(4) initiating system in hexane/methyl chloride (60:40 v/v) solvent mixture at -80 °C. (1) H NMR spectroscopy verified the incorporation of one epoxy-POSS per polymer chain. Light scattering and TEM analysis demonstrated the formation of 50-100 nm sized aggregates and micron-sized clusters.
