摘要 |
<p>A composition of ethylene polymers of relative density at least 950 kg/m<3>, melt fluidity index MI5 of 0.05-2 g/10min and a 4-10C alpha-olefin content 0.15-1% by moles (mol.%) comprising 53-63% by weight (wt.%) of an ethylene polymer and 37-47 wt.% of a copolymer of ethylene and one or more 4-10C alpha-olefins. The ethylene polymer has melt fluidity index MI2 at least 100 g/10min, relative density at least 969 kg/m<3> and polydispersity index above 4. The copolymer has alpha-olefin content 0.32-2.7 mol.%, MI5 0.001-0.5 g/10min, relative density 930 kg/m<3> or more and polydispersity index above 4. An Independent claim is included for pipes manufactured from the composition.</p> |
