Dzinyak B. Scientific Foundations and Technology of Cooligimers from By-Products of Hydrocarbon Pyrolysis

The thesis is dedicated to the development of scientific basis and creation of technology of cooligomers (petroleum resins (PR)) based on the hydrocarbon fractions of liquid pyrolysis by-products of ethylene productions. The main regularities of fractions C5 and C9 unsaturated hydrocarbons cooligomerization initiated by peroxides, as well as regularities of PR modification with unsaturated acids and anhydrides have been determined. Selected optimal technological parameters of processes. Technology of PR synthesis by initiated cooligomerization of C9 fraction unsaturated hydrocarbons have been created. The developed technology has been implemented at "Oriana" Joint-Stock Company (Kalush).
