ABSTRACT
The decomposition products of phenol derivatives under the electron discharge action are described, and their decomposition processes are analyzed. The characteristics of the processes showed general regularities in the plasma impact on phenol and its derivatives. It is shown the decomposition kinetics has a pseudo-first order for the substance concentration. The order of magnitude of the velocity constants is the same; plasma-forming gases have the same regularities. The solution pH tends to the alkaline part under the discharge action. It is also described the addition of the •OH radical trap and the Fenton reagent have the same effect on the decomposition of phenol and its derivatives..
KEYWORDS: electronic discharge, phenol, phenol derivatives.

ABSTRACT
The coagulating ability of two cationic electrolytes — cetylpyridinium bromide and cetyltrimethylammonium bromide and a combined coagulant based on sodium chloride and the above two cationic electrolytes on the process of rubber isolation from latex was assessed. It has been established that the completeness of coagulation is affected by the consumption of coagulating and acidifying agents. The use of a combined coagulant makes it possible to achieve the complete release of rubber from latex at asodium chloride consumption of about 120 kg / t of rubber and a cationic electrolyte consumption of 10 kg/t of rubber. By their main indicators, the resulting rubbers and vulcanizates correspond to the requirements.

INFLUENCE OF E-181 EPOXY RESIN ON NBR BASED RUBBERS (p. 40-44)

ABSTRACT
There was investigated the influence of E-181 epoxy resin on properties of NBR (28% acrylonitrile content) based rubbers. It was found out that if epoxy resin content is 10 phr. then the best tensile strength (1,2-1,8 times more) and better elongation at break can be provided after open air aging at 120°C. The achieved positive effect on improving the dynamic properties and wear resistance is due to the reactions of grafting of the resin to the rubber macromolecule, which can take place both at the stage of rolling and at the stage of vulcanization. For the maximum modifying effect, it is proposed to introduce epoxy resin directly into the rubber, followed by processing on rollers for 3-5 minutes. Different times of rubber rolling in the presence of epoxy resin and different order of E-181 introduction are due to the fact that it was necessary to assess the influence of these parameters on the modification features in terms of the efficiency of grafting reactions, as well as on the final properties of rubber. After exposure in diesel fuel at 100°C the modified rubbers show lower properties deterioration. E-181 epoxy resin influence on lowtemperature properties was also investigated..

ABSTRACT
The effect of boron nitride on the rheometric and physicomechanical properties of the rubber mixture and vulcanizates based on the hydrogenated nitrile butadiene rubber Terban 3406 is investigated. It is established that hexagonal boron nitride has practically no effect on the kinetics and duration of vulcanization of the rubber mixture. An increase of content boron nitride in the rubber mixture leads to an increase in stress at a given elongation and tear resistance at room temperature of the vulcanizates, a slight increase of their elastic strength at 150°C and temperature of the onset of destruction.
KEYWORDS: hexagonal nitride bor, rheometric, physical and mechanical properties, hydrogenated butadiene-nitrile caoutchouc Terban 3406, rubber mixture, vulcanizates.
