Abstract—The catalytic activity of linear and network oligomer copperorganosiloxanes immobilized on the
surface of Silochrome in a reaction of CCl₄ addition to olefins was studied. It is likely that the reduction of
Cu(II) ions to Cu(I) is a step in the catalytic radical reaction studied. This process also occurs in the absence of
reagents at relatively low temperatures. The reaction occurs more readily in linear polycopperorganosiloxanes
than in the network oligomers, which is consistent with the catalytic activity. The studied catalytic reaction is
characterized by an unusual dependence of the activity of polycopperorganosiloxanes on metal concentration.
