Described herein are butt-welded polymeric articles and means of effecting joinder of crosslinked polymeric articles by means of such welds. The invention finds application in, e.g., forming large-diameter heat recoverable sleeves from cross-linked polymeric sheet for, e.g., corrosion-proofing pipe joints and the like. The weld is effected by heating under compression a thermoplastic insert containing a peroxide or other heated-activated crosslinking agent. |
