author S.P.Prokopchuk (Kosmonavtiv avenue 12, ap.30, Vinnytsia, Ukraine, 21021) |
S.P.Prokopchuk Synopsis: Modification of thermoplastic polymers (polystyrene, vinyl acetate, polyacrylates, polyvinyl chlorides) by introduction of oxygen or oxygen containing gas (air) into monomer polymerization zone and heating of the peroxicontaining polymer which is being formed to 110-180 o C. The ways of utilization of modified polymers to produce electric insulating, thermo insulating and soundproof materials, construction, corrosion protective, fiberglass plastic and impregnation materials; radiation protective materials, corrosion-proof products and anticeptic, anaesthetic preparations are offered. |

author S.P.Prokopchuk (Kosmonavtiv avenue 12, ap.30, Vinnytsia, Ukraine, 21021) |
S.P.Prokopchuk Synopsis: it gives a short description of influence of the catalysts, polar solvents, reaction duration, temperature, pressure, hydrocarbons concentration in the reaction mixture, oxygen concentration in the oxidating gas, addition of water into the oxidation zone, removal of the reaction products out of the oxidation zone, step-by-step temperature change in the oxidation zone, step-by-step introduction of the oxygen containing gas into the oxidation zone on yield and selectivity of end products formation at hydrocarbons liquid phase oxidation. |
