| titleOfInvention | Polypropylene for foamed plastic and foamed polypropylene |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a polypropylene composition for foamed plastic, a method of obtaining the polypropylene composition and the foamed plastic and to foamed products, obtained from the polypropylene composition. The composition contains a polypropylene basic polymer in a quantity not less than 96 wt % of the total weight of the polypropylene composition and the content of substances, non-soluble in hot xylene, in a quantity from 0.10 to 0.30 wt % of the total weight of the polypropylene composition. The composition has an index of melt fluidity (ILF 2 ) which constitutes at least from 1.0 to 5.0 g/10 min, melt strength F30 - not less than 30 cN, determined in the Rheotens test at 200°C, and melt tensility v30 - of less than 200 m/s, determined in the Rhoetens test at 200°C. The method of the composition obtaining includes obtaining an intermediate polypropylene, which has MFI 2 in a quantity from 0.5 to 2.5 g/10 min, in the presence of an asymmetric catalyst. After that, the intermediate polypropylene is mixed with peroxide and at least one diene at a temperature, which constitutes from 20 to 90°C, for not less than 2 minutes with the formation of a preliminarily mixed material, with the following mixing in a mixing device in a melt at a temperature of an extruder cylinder from 180°C to 300°C. n EFFECT: composition improvement. n 14 cl, 3 tbl, 8 ex |
