The results of experimental researches of features of mechanical activation of polyethylene granules with finely dispersed zinc in a ball mill, and also results of research of chemical copper plating of activated polyethylene granules are given. The influence of the ratio of polyethylene granules and fine zinc, the speed of rotation of the ball mill and the duration of activation, as well as the degree of loading of the components in the activation process of polyethylene granules was studied. It is established that the condition of activation of polyethylene granules with finely divided zinc has a significant impact on the metallization process and the copper efficiency of activated polyethylene granules.

The results of experimental studies of copper plating of polyvinyl chloride granules in a chemical precipitation solution are presented. The influence of the surface area of polyvinyl chloride granules on the kinetic regularities of copper reduction and the copper content on metallized granules has been studied. It is established that the surface area of polyvinyl chloride granules has a significant effect on the rate of reduction of copper ions and does not affect the amount of reduced copper. The thickness of the layer of the obtained copper shell on polyvinyl chloride granules of different sizes depending on the metal content is calculated.

The geometric dimensions of the copper shell formed by chemical deposition on a spherical polyethylene granule were calculated. It is shown that the main factor determining the thickness of the formed copper layer is the initial size of the polyethylene granule. The processes of destruction of the copper shell formed on the polyethylene granule during thermal expansion of the polymer are considered. The values of the limit temperatures in which the copper shell still retains its integrity depending on its thickness are calculated.
