Preparation of Polyethylene Wax from LDPE in the Solvent

Abstract:

Polyethylene wax is prepared from LDPE through orthogonal experiments. It is found that temperature, time and the ratio of solvent to the feed can affect the experiment. The optimal condition is 310°C, 5h and 1 : 1.5. The result of experiment under the optimal condition is better than that in the orthogonal experiments. The color of products is from white to yellow. Finally, PEW is obtained from pyrolyzing waste PE bag under the optimal condition and the best condition in the orthogonal experiments. It can be seen that the former result is better than the later. The average molecular weight of polyethylene wax ranges from 1970 g/mol to 2700 g/mol.
