Chemical modification of an industrial waste (atactic polypropylene) using a two-step process to obtain a fluorescent-modified polyolefin is the subject of this article. For these purposes, a Box-Wilson statistical experimental design has been used. The product was obtained by a condensation reaction after a previous one via a radical reaction had taken place in the melt. Furthermore, the nature of this product reveals that only single succinic anhydride groups were previously grafted onto polymers coming from the previous radicular reaction.
