Rheological properties of melts and x-ray method of study of cross-linked polyethylene

Abstract

In the paper, the X-ray study of cross-linked polyethylene with isopropenyl styrene or acrylonitrile was carried out. It is shown that cross-linking leads to a significant decrease in the area of the exothermic peak, an increase in the resistance of the structured system to thermal oxidation. These data confirm that the increase in resistance to thermal aging of polyethylene crosslinked with acrylonitrile or isopropenyl styrene fraction.
