Water-assisted extrusion of polypropylene/clay nanocomposites: A comprehensive study  
(443-451) Polymer 52 #2 (2011)
Rousseaux et al of the Université Catholique de Louvain, Belgium obtained the best clay dispersion and properties improvements of PP-g-MA/organoclay nanocomposites and masterbatches were obtained using high-shear rates and water injection (synergy effect). The nanocomposites prepared by dilution into PP of a masterbatch prepared through water-assisted extrusion showed the highest clay dispersion and consequently the best thermal, mechanical and rheological properties.  (RDC 1/27.2011)
