Slieptsov A. Technology development of polyolefins grafted maleic anhydride and their application.

The thesis is devoted to developing ways to improve technologies for polyolefins grafted maleic anhydride. An regularities of functionalization of polyethylene wax that revealed rational technological modes of obtaining polyethylene wax with a high degree of grafting maleic anhydride. The mechanism of mutual influence the content of maleic anhydride, DCP and parafine oil in the process of obtaining polyolefins, functionalized maleic anhydride by the reaction extrusion, determined their impact on the degree of grafting maleic anhydride. Improved technology for polyolefin, maleic anhydride functionalized through the implementation process of vacuum evacuation of maleic anhydride residues that do not react with the finished product. The main stages and the rational technological parameters of obtaining polyolefines functionalized by maleic anhydride, the reaction by methods of extrusion and solid-phase functionalization was justified on the basis of the obtained results.
