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

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 cross-linked with acrylonitrile or isopropenyl styrene fraction.

Application of Vacuum Distillation for the Used Mineral Oils Recycling

The physico-chemical properties and the group composition of the used mineral motor oils M-10DM and NORMAL 15W40, as well as the fractions obtained as a result of their vacuum distillation, have been studied. The results of IR spectroscopy and XRF analysis are presented. The change in the composition and properties of the fractions distilled from used oils under vacuum has been described.
