Abstract: The invention relates to an improved process for controlling the amount of crosslinking in polyolefin based articles such as fibers or films. The invention relates to mixing silane grafted material together with ungrafted material prior to crosslinking. The article can then be formed and cured, optionally with a curing catalyst which can preferably be applied to the surface of a shaped article. The amount of crosslinking will be controlled in part by the level of silane grafting on the grafted silane material as well as the amount of the grafted material in the blend.
