Abstract
Inventia se refera la un procedeu de obtinere a polietilenei pentru fabricarea rafiei sintetice, prin polimerizarea în suspensie a etilenei, într-un singur reactor, la temperaturi de 50 ... 150 grade C, de preferinta 75 ... 85 grade C, la presiuni de 0,1 ... 2,0 MPa, de preferinta 0,3 ... 0,7 MPA, cu catalizator compus de titan impregnat pe un suport de baza de MgCl indice 2, densitatea polietilenei fiind reglata în domeniul 0,94 ... 0,95 g/cm cub prin copolimerizarea etilenei cu o alfa-olefina, de preferinta propilena. Se obtine o polietilena cu etirare uniforma.The invention relates to a process for obtaining polyethylene for the manufacture of synthetic raffinate by suspending polymerization of ethylene in a single reactor at temperatures of 50 DEG to 150 DEG C., preferably 75 DEG to 85 DEG C., to pressures of 0.1 ... 2.0 MPa, preferably 0.3 ... 0.7 MPA, with titanium compound catalyst impregnated on a basic MgCl index of 2, the density of polyethylene being set in the range of 0, 94 ... 0.95 g / cm cube by copolymerization of ethylene with an alpha-olefin, preferably propylene. A uniform polyethylene is obtained.
