Abstract: The present invention is directed to PE-100 ethylene copolymers and pipe made thereof having a Tabor abrasion between about 0.01 and about 0.001 grams lost/1000 revolutions. These copolymers are formed by contacting ethylene with at least one mono-1-olefin comonomer having from 2 to about 10 carbon atoms per molecule in a reaction zone under polymerization conditions in the presence of a hydrocarbon diluent, a catalyst system, and a cocatalyst. Additionally, the comonomers may be selected from mono-1-olefins having 4 to 10 carbon atoms, such as, 1-hexene, 1-butene, 4-methyl-1-pentene, 1-octene, and 1-decene. Further, these ethylene copolymers may be employed to produce PE-100 pipe having both small diameters and diameters in excess of 42 inches substantially without sagging or other gravitational deformation. Copolymers of ethylene and 1-hexene are disclosed which are used to produce PE-100 pipe.

Abstract: A catalyst system composition comprising a chromium compound supported on a silica-titania support, wherein said catalyst system has been reduced with carbon monoxide, and a cocatalyst selected from the group consisting of i) alkyl lithium compounds, ii) dialkyl aluminum alkoxides in combination with at least one metal alkyl selected from the group consisting of alkyl zinc compounds, alkyl aluminum compounds, alkyl boron compounds, and mixtures thereof and iii) mixtures thereof can be used to polymerize olefins to produce a low density polymer with a decreased melt index and/or high load melt index. This catalyst system also can be used with a Ziegler-Natta catalyst system to polymerize olefins. Polymerization processes using these catalyst system compositions are also provided. Polymers resulting from polymerization processes using the inventive catalyst and cocatalyst systems have a decreased high load melt index, decreased melt index, increased fluff bulk density, and are useful as components to make bi-modal molecular weight resins for film and/or blow molding applications.
