In this study, composites based on polypropylene and single-wall carbon oxygen-containing nanotubes were successfully synthesized using a specific catalytic system in liquid propylene medium. It was found that the presence of functional groups enhanced the agglomeration tendency of the filler, while the filler inhibited the oxidation and destruction processes of polypropylene crystallites.
Composites based on polypropylene and single-wall carbon oxygen-containing nanotubes with a specific surface area of 360 and 500 m(2)/g are synthesized in the medium of liquid propylene using the catalytic system rac-Me2Si(2-Me-4-PhInd)(2)ZrCl2/\MAO. Optimum polymerization conditions ensuring a fairly high rate of the process are determined, and the composites with the filler content in the range from 0.3 to 13.0 wt % are obtained. It is shown that the presence of functional groups enhances the filler agglomeration tendency during composite formation. Effects of the type of carbon nanofiller on the thermal stability, thermo-oxidative resistance, and thermal and electrophysical characteristics of the composites are studied. It is found that the filler inhibits the processes of oxidation and destruction of polypropylene crystallites.
