| Abstract: | Polypropylene (PP) having high melt strength was prepared by means of radiation process. Its physical and mechanical properties, melt strength, elongational viscosity and melt sag were measured. The effects of absorbed dose, sensitizer concentration and kinds, heat treatment, etc., on melt strength were studied in detail. On the basis of the PP so prepared, a kind of foam product with foaming ability of 15 times of volume was also prepared. |

| Keywords: | polypropylene melt strength radiation foaming thermoforming. |
