<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing a crosslinking olefin resin tube capable of simply manufacturing the crosslinking olefin resin tube of a stable quality by suppressing a thermal deterioration of a resin by using a water crosslinking method of a silane modified olefin resin. SOLUTION: The method for manufacturing the crosslinking olefin resin tube comprises the steps of adding at least an olefin resin powder, an ethylenic unsaturated silane compound and a radical generating agent to an olefin resin pellet, mixing them, then supplying a mixture to a hopper of an extruder, melt kneading the mixture to modify the olefin resin with the ethylenic unsaturated silane compound, melt extrusion molding the mixture in a tubular state to a modified olefin resin tube, and then bringing the tube into contact with the moisture in the presence of a silanol condensation catalyst to form the crosslinking olefin resin tube.</p> |
