Kinetics Of High Solid Contents Copoly (Styrene/ Butyl Acrylate) -Montmorillonite Nanocomposites

Miniemulsions are submicron dispersions of monomer in water with droplet size between 50 and 500 nm, which are formed by the high shear homogenization of a crude emulsionand unique droplet nucleation mechanism during polymerization. Already exfoliation of Cloisite®30B (anorganically modified MMT) clay concentration up to 5 wt% and total latex solid contents of 20% was reported [1]. In this study, nanocomposite latex particles including Cloisite®30Bup to 10 wt% with solid contents of 20 and 40% was synthesized respectively. Kinetically studies was accomplished and revealed that in higher concentrations, clay behavior was quite different
