  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.

  将非极性合成树脂与具有附图所示配方的过氧化物混合，并在除上述过氧化物外没有任何极性辅助物质的情况下，将混合物置于高频交流电场中，非极性合成树脂就会发生交联。 这样固化的聚合物具有良好的电气性能，非常适合用作电缆的绝缘材料。
