Abstract:
This invention relates to a polymeric pipe, and more particularly a polymeric pipe where the pipe comprises a crosslinked polyolefin formed from extruded polyolefin comprising a photoinitiator and a reactive extrusion species. More particularly, this invention relates to the manufacturing of plastic pipes and tubing by utilizing co-rotating twin screw extrusion combined with photo-induced crosslinking, of thermoplastic polymers such as polyethylene, to produce PEX pipes and tubing.

Claim (Index 6):
A polymeric pipe formed from:\n a polyolefin structural polymer; a photoinitiator in an amount of 0.02 to 3% by weight, and a scavenger in an amount of 0.01 to 2% by weight; wherein the photoinitiator is a compound of formula I: wherein: R 1  is selected from \u2014(CH 2 ) m (C\u2550O)[O(CH 2 ) n ] p O(C\u2550O)(CH 2 ) q \u2014, \u2014(C\u2550O)(C 5 -C 24  alkyl), and \u2014(C\u2550O)(C 5 -C 24  alkenyl); R 2  is selected from \u2014H, \u2014OH, -halo, \u2014(C 1 -C 4 )alkyl, \u2014(C 2 -C 4 )alkenyl, and formula II: R 3  is selected from \u2014H, -halo, \u2014OH, \u2014(C 1 -C 4 )alkyl, \u2014(C 2 -C 4 )alkenyl, \u2014O(C 1 -C 4 )alkyl, and \u2014O(C 2 -C 4 )alkenyl; m is 0, 1 or 2; n is 2, 3, 4, 5, 6; p is 2-10; and q is 0, 1 or 2.
