Butt-welded polymeric articles and means of joining crosslinked polymeric articles by means of butt welds. The invention finds application in, e.g., forming large-diameter heat recoverable sleeves from crosslinked polymeric sheet for, e.g., corrosion-proofing pipe joints. The weld is effected by heating under compression a thermoplastic insert containing a peroxide or other heat-activated crosslinking agent. |
