| titleOfInvention | Method for High Pressure Preparation of Free Radical Ethylene Copolymer |
| abstract | The present invention provides a high pressure polymerization process for forming an ethylene-based polymer, the process comprising the steps of: polymerizing a reaction mixture comprising ethylene and at least one comonomer using a reactor system comprising a reactor configuration as follows: (A) at least two reaction zones, a first reaction zone (reaction zone 1) and an ith reaction zone (reaction zone i, where i ≥ 2), (B) at least two ethylenic feeds As a stream, each feed stream comprises a percentage of the total make-up ethylene fed to the polymerization process, wherein the first ethylene-based feed stream is sent to reaction zone 1 and the second ethylene-based feed stream is sent to reaction zone at least two ethylene-based feed streams sent to i; a control system for regulating the percentage of, wherein the ratio of the molar concentration of at least one comonomer fed to the first reaction zone to the molar concentration of comonomer in the sum of all ethylene-based feeds to the reactor configuration (Q ) satisfies Equation 1: 0.23 In(r1) - 2.16 ≤ Q ≤ -0.25 In(r1) + 2.15 (Equation 1); The comonomer has a reactivity ratio (r1) as follows: 0.3 ≤ r1 ≤ 5.0, and a boiling point (1 atm) ≤ 150°C. |
