摘要：
Pyrolysis of high density polyethylene (HDPE) to polyethylene wax (PEW) in a 1 L continues stirred-tank reactor (CSTR) was studied at 360-420 degrees C with 5-240 min, yield of PEW was discussed and the properties such as the drop melting point and average molecular weight of wax were determined. The PEW had a melting point of 104-120 degrees C, and an average molecular weight of around 3000 with a good dispersity at 673 K.,Moreover, the composition of wax determined by fourier transform infrared spectroscopy (FT-IR) indicated that it was less branched than commercial waxes.
