| titleOfInvention | Method for high-temperature solution polymerisation of polyethylene |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for polymerisation of ethylene and one or more C3-30 -olefins or diolefins in continuous solution polymerisation conditions to obtain a high-molecular weight polymer. The method involves carrying out polymerisation in the presence of a catalyst composition containing a cocatalyst and a zirconium or hafnium complex of a polyvalent aryloxyether of formula: , where M3 is Hf or Zr, preferably Zr; Ar4 has the formula: , where R11, in each case independently, denotes hydrogen, hydrocarbyl containing up to 50 atoms not counting hydrogen, under the condition that in at least one case, R11 is spatially volumetric; T4, in each case independently, denotes a C2-20 alkylene group; R21, in each case independently, denotes hydrogen, hydrocarbyl containing up to 50 atoms not counting hydrogen; R3, in each case independently, denotes hydrogen, hydrocarbyl containing up to 50 atoms; RD denotes a hydrocarbyl group containing up to 20 atoms not counting hydrogen. At least two R3 groups located on different arylene-oxy groups are spatially volumetric. The polymers have molecular-weight distribution (Mw/Mn) of less than or equal to 3.0. Content of comonomer gives the polymer density of 0.850-0.950 and the polymer has properties l10 and I2 which satisfy the relationship I10/l2ëñ10,32 (MI)-0.0814 for values of MI in the range of 0.01-50. A metal complex of a polyvalent aryloxyether is also disclosed. ^ EFFECT: invention enables to obtain improved polymers. ^ 20 cl, 1 dwg, 3 tbl, 8 ex |
