Al'mauri S. Elaboration of technology of obtaining the petroleum resins with hydroxyl groups.

The thesis is concerned wiht the problem of pyrolysis by-products into (namely fraction C9( rational utilization. A number of unsaturated compounds are contained in hydrocarbons C9, which are able to interact polymerization or oligomerization process. Petroleum resins with hydroxyl groups (PRH) have been synthesized by initiated oligomerization of above-mentioned compounds in the presence of Azopentanole. Influence of the main factops upon eield and characteristics of PRH has been studied. Synthesized petroleum resins with hydroxyl groups are represended. With the aim of increasing the yield and obtaining the qualitativly new PRH, the oligomerization process of fraction C9 with styrene has been studied.The modification process of PRH with maleic anhydride was studied. Synthesized petroleum resins with hydroxyl groups have been used for formation of block-copolymers with industrial epoxy resin ED-22. Block-copolymers on the basec of PRH can be applied as components of protective coatiogs. Principal tech nological scheme of PRH has been proposed.
