green methods for their synthesis are still being sought. Herein, ultrasound-assisted synthesis of dialkyl peroxides from alkyl hydroperoxides and alkyl bromides in the presence of an aqueous solution of an inorganic base was systematically studied underphase-transfer catalysis (PTC) conditions. The process run in a tri-liquid system in which polyethylene glycol as a phase-transfer catalyst formed a third

Non-polar synthetic resins are cross-linked by mixing the resin with a peroxide having a formula illustrated in the accompanying drawing and exposing the mixture to a high frequency alternating current field in the absence of any polar auxiliary substance other than said peroxide.
The polymers thus cured have favourable electrical properties and are very suitable to be used as insulating material for electrical cables.
