Impact of toluene sorption on oligomers and antioxydants migration from HDPE pipes

Impact of toluene sorption on oligomers and antioxydants migration from HDPE pipes

The objective of this work was to investigate the ageing behaviour of filled HDPE samples, immersed into toluene at 60 °C, in terms of migration and extraction of stabilizers and oligomers. Firstly, the high level of solvent solubility (mass uptake of∼13.6 wt%), due to the high toluene/HDPE affinity...
