Synthesis of Poss-functionalized Polyisobutylene via Direct Initiation
POSS-functionalized polyisobutylenes (PIBs) were synthesized by carbocationic polymerization using an epoxy-POSS/TiCl4 initiating system in hexane/methyl chloride (60:40 v/v) solvent mixture at −80 °C. 1H 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.
