反応手順
These blends were then added at 1000 ppm to Profax 6501 polypropylene along with 500 ppm of a hindered phenol antioxidant, namely tetrakis[methylene(3,5-di-t-butylhydroxyhydrocinnamate)]methane (DOVERNOX 10); octadecyl 3,5-di-t-butyl-4-hydroxyhydrocinnamate (DOVERNOX 76); and 1,3,5-tris(3,5-di-t-butyl-4-hydroxylbenzyl)-1,3,5-triazine-2,4,6(1H, 3H,5H)-trione (DOVERNOX 3114), and 500 ppm calcium stearate. The polymer was then subjected to multiple pass extrusion as described in Example 1. A comparison was made with multiple pass extrusions in which TNPP was substituted for the blend. The results are given in Table 2
