kinethical aspects of high solid contents copoly(styrene/butylacrylate)-cloisite 30b nanocomposites

high solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of cloisite 30b (7 wt% and 10 wt%) were kinetically investigated. gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. results showed that by increasing the solid content; the average diameter of polymer particles decreased. studies on the polymerization rate depict that the increase in polymer particle size provides more average reactive radicals per polymer particle, which increased from 0.48 to 0.88 for the sample containing 7 wt% clay and 20 wt% solid content. observed armored particles with honeycomb morphology is the most novelty of this research work, which is suitable for making barrier packaging films.
