PROBLEM TO BE SOLVED: To provide a method to enable the material recycling of a polypropylene and to obtain the regenerated polypropylene by recovering mechanical property and rigidity, when the property of the polypropylene resin collected from waste electric appliances is degenerated by contamination with foreign substances during its long term use. SOLUTION: The regenerated polypropylene contains 30-70 pts.wt. resin reinforcing agent which is a polypropylene resin having a reactive group in its skeleton per 100 pts.wt. collected polypropylene resin, and the reactive group is preferably an active silane group.
