Cross-linkable polymers are prepared by the introduction of the cross-linking agent to the main body of the polymer to be cross-linked in an extruder. This method reduces the "heat history" of the cross-linkable polymer and allows greater pre-extruder processing flexibility. Thus, mixing times can be reduced and the shelf life of the pre-extruded polymeric composition can be extended. After extrusion, the product may be cross-linked by heating.
