Coefficients of linear thermal expansion (CTE) for poly(propylene)/ poly(propylene)-grafted-maleic anhydride/montmorillonite ethylene-co-octene elastomer (PP/PP-g-MA/MMT/EOR) blend nanocomposites were determined as a function of MMT content and vario

A silanized organoclay (s-M2(HT)2) was prepared by reaction of trimethoxyphenyl silane with an organoclay with a M2(HT)2 surfactant structure. Nanocomposites were formed from polypropylene (PP) and a blend of PP and maleic anhydride-grafted polypropy

Part 1 of this series showed that the purification level and surfactant loadings of organoclays significantly affect their thermal stability; the higher rate of degradation of as-received commercial organoclay is primarily a result of excess surfacta
