A process for the preparation of ethylene homo- or copolymers in a tubular reactor |
| abstract |
The invention relates to a process for the preparation of low density polyethylene (LDPE) wherein the polymerisation takes place in a tubular reactor at peak temperatures ranging from 180 °C to 350 °C and at pressures ranging from 150 to 350 MPa and wherein the total effective length of the polymerisation reactor divided by the number of reaction zones is in the range from 230 to 350 m. |
