20 claims: 3 independent, 17 dependent

  1. 1
    Claims of equivalent WO 2014120540 A1 CLAIMS 1. A polymer reactor-blend comprising at least a first component having a polydispersity index of greater than about 20 and present in an amount of from about 1 wt.% to about 99 wt.% based on the total weight of the polymer and a second component having a polydispersity index of less than about 20 and present in an amount of from about 1 wt.% to about 99 wt.% based on the total weight of the polymer wherein a molecular weight distribution of the second component lies within a molecular weight distribution of the first component.
  2. 15
    A method of preparing a polymer pipe comprising:obtaining a polymer prepared by contacting ethylene monomer and 1-hexene with a catalyst composition comprising (i) an imine (bis) phenolate compound having Structure XIV Structure XIV where M is a Group 3 to Group 12 transition metal or lanthanide R 2 and R 3 can each independently be hydrogen, a halogen, a hydrocarbyl group, or a substituted hydrocarbyl group and (ii) a metallocene complex under conditions suitable for the formation of a polymer and Et20 is optional;and fabricating the polymer into a pipe wherein the polymer has zero shear viscosity of from about 1E+05 Pa-s to about lE+10 Pa-s and a tensile natural draw ratio of less than about 600 % and wherein the pipe has a PENT value of greater than about 800 hours as determined in accordance with ASTM F1473 using a 3.8 MPa stress.
  3. 16
    A polymer reactor blend having a polydispersity index of greater than about 15 and a short-chain branching distribution maximum that occurs between a weight average molecular weight of about 30 kDa and 1000 kDa.
