Synthetic Route
| With high-purity ethylene as the main raw material, propylene, 1-butene, etc. as the copolymer monomer, and hexane as the solvent, the polymerization is carried out under low-pressure conditions of about 78℃~85℃ and 0.13MPa~0.70MPa using a highly active catalyst, and then dried, mixed, extruded, granulated, sieved, and homogenized to obtain polyethylene particles with a density of 0.940g/cm3~0.970g/cm3. |
