摘要: Abstract A study on the thermal behavior and flammability properties of heterophasic polypropylene–(ethylene–propylene) copolymer (PP–EP)/poly(ethylene vinyl acetate) (EVA)/montmorillonite nanocomposite is presented. Nanoclay nanocomposites were prepared using a twin screw extruder. Both fluidity EVA phase compatibility conditions between PP–EP used in order to obtain required nanocomposites. Therefore, no additional compatibilizer was achieve clay dispersion. Products exhibited partially exfoliated/intercalated nanoclay Thermogravimetric analyses indicated that nanoclays retard degradation depending concentration. The retarding process assigned exfoliation dispersion silicate layers which impeded heat diffusion macromolecules. Thermal studies, under non-isothermal crystallization, lack influence behavior. Flammability characteristics however affected by overall generated flame retardation both host complex
