Abstract

By the example of polypropylene-organic montmorillonite composite (PP-OMMT), the abilities of the method of equal channel multiangular extrusion have been studied with respect to the modification of the structure and the properties of polymeric nanocomposites. With using X-ray structure analysis, TEM, DSC, and dilatometry, it has been demonstrated that this kind of processing providesanadditionalintercalationofthepolymerintoOMMTtactoidswiththesucceedingexfoliationandfacilitates anincreaseintheaspectratio, the degree of plateletorientation,the crystallinelamellarthickness,andadecreaseinthedispersion of the crystallite thickness, as well as the formation of biaxial orientation of the OMMT and PP crystals. The observed structure rearrangementsdetermineenhancedmicrohardness,ductility,andtheheatdistortiontemperatureofthePP-OMMTcomposite
