Abstract
A homogenous, free-flowing, resin containing 80 to 90 weight percent of polypropylene and 10 to 20 weight percent of liquid organic peroxide, where the weight percents are based on the total weight of the polypropylene and the liquid organic peroxide, is provided. Furthermore, a process is provided for producing this polypropylene by mixing 80 to 90 weight percent of polypropylene, in the form of 100-500 micron particles, with 10 to 20 weight percent of liquid organic peroxide, where the weight percents are based on the total weight of the polypropylene and the liquid organic peroxide.
