摘要
In this paper the authors report preliminary results on the use of near-critical difluorodichloromethane (Freon 12) for extracting low-molecular-weight oligomers from polyethylene film. Both linear low-density (LLDPE) and low-density (LDPE) polyethylene films are used in this study. This study demonstrates the potential of using supercritical fluids for processing or treating polymers.
