The new free-radical initiators were prepared from the commercially available substrates: 60% hydrogen peroxide, ethyl methyl ketone, 1,2-propanodiol and high-molecular compounds containing hydroxylic groups such as hydroxypolyethers D 1002, D 2002, F3600T. 1,2-propanodiol and hydroxypolyethers were used as solvents of the hydroperoxide compounds. Such physical properties as density, viscosity, concentration of active oxygen and temperature of decomposition were determined for the synthesized initiators and Luperox using the differential scanning calorimeter. The unsaturated polyester resin Polimal 109 was used to determine the efficiency of the new initiatiors in the curing procedure at room temperature. The properties of the resin in the process of crosslinking and after curing were compared with the new initiators and the typical curing system containing ethyl methyl ketone hydroperoxide (Luperox) and cobalt (II) octoate.
