Abstract
The general scheme by which a single steric network forms during the heterogeneous vulcanization of elastomers, using unsaturated compounds, has been evaluated. An oriented polymer layer is assumed to form at first at the interface with the dispersed particles of the curing agent, and the adsorbed macromolecules position themselves as folded structures on the surface. The crosslinking takes place as a result of chemical reaction of the curing agent with some of the loops of the adsorbed macromolecules. A single steric network will form when the chain units of a single folded macromolecule react with various particles of the curing agent. In addition to the heterogeneous network there is also some chemical union between chains due to reactions of the dissolved peroxide present.
