PROCESS FOR MODIFYING THE RHEOLOGY OF POLYOLEFINS |
摘要 |
The molecular weight of a polyolefin such as polypropylene is reduced, as evidenced by lowered viscosity and increased melt flow rate, by treatment with an inorganic peroxygen selected from metal persulfates, ammonium persulfates, and any mixtures thereof. The treatment avoids or minimizes the color or odor attendant treatment with organic peroxygens and the toxic products of organic persulfate decomposition, and avoids the special handling required with organic peroxides. |
