Abstract: 
The initiating properties of urea-formaldehyde oligomers with peroxide groups have been studied. For comparison, the initiating activity has been examined for the polymerization of styrene by the peroxide oligomer based on the epoxy oligomer Epidian-5 and tert-butyl hydroperoxide. The cross-linking properties of the urea-formaldehyde oligomers with peroxide groups have been investigated using unsaturated oligoesters as a model. The chemistry of the formation of the substances with a cross-linked structure has been studied using IR spectroscopy.
