Chajkivs'kyj O. Technology of obtaining of petroleum resins with end carboxyl groups.

Dissertation is dedicated to elaboration of petroleum resins with carboxil end groups (PRC) obtaining on the basis of fraction C9 of hydrocarbons pyrolysis and also difunctional initiators. The method of PRC obtaining under condition of initiator constant rate decomposition has been proposed using the planned increasing temperature. Need of rectification processes carrying out during raw material preparation has been determined. Sampling the solvent and synthesis of PRC were jointed into one stage. It has provided the product obtaining with functionality 1.94 and number average molecular mass equal 2060. Yield on the basis of rectificate consists 23.5%. Composition of PRC with epoxy resins were studied. The main possibilities of their practical applications have determined.
