| Use | is used as pour point depressant in oil well production. |
| production method | 1 000 kg of benzene and 80 kg of vinyl acetate were sequentially added to the polymerization vessel, and then the reactor was cleaned with nitrogen, the ethylene was washed again, then heated to 105 ° C., and the ethylene was pressed in until the pressure rose to 6.38 MPa. The vinyl acetate was continuously pumped into 2.5/h for a total of 290 within hours. The catalyst dilauroyl benzene peroxide solution (2.5/h) was added continuously at a constant rate over 100 h for a total of 250. The reaction was carried out at 105 °c for 10 min and cooled to 60 °c. The solvent was purged with nitrogen to give a white emulsion. |
