Influence of supercritical CO2 on the interactions between maleated polypropylene and alkyl‐ammonium organoclay

Abstract Supercritical carbon dioxide (scCO 2 ) has been proposed as an effective exfoliating agent for the preparation of polymer‐layered silicate nanocomposites, though there is limited fundamental understanding of this mechanism. This study looks at the interactions of this unique green solvent with three maleated polypropylenes of varying anhydride content and molecular size with an alkyl‐ammonium organoclay. Mixtures of compatibilizers …
