摘要：There are described thermoplastic polypropylene pellets of improved processability containing a free radical source prodegradant which on remelting the pellets by extruding or the like, will react to further reduce the molecular weight as well as the molecular weight distribution of the polymer to a point where high capacity production of quality fibers and extruded products can be obtained. The free radical material has a 1 DIVIDED 2 life in polypropylene in excess of 1 DIVIDED 2 minute at 190.56 DEG C.
