摘要 |
A method for producing a polypropylene blend from a plastic packaging materials containing high molecular weight polypropylene, other high molecular weight polymers such as polyethylene, low molecular weight polymers and other contaminants. The method includes extraction, solid-liquid separation and liquid-liquid phase separation using various organic solvents. The polypropylene blend has a purity of 95% and has favorable melt flow characteristics, while retaining satisfactory mechanical properties.
