| 摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to composition for beta-nucleation of polypropylene and method of its obtaining. Composition represents particles of natural mineral solid substrate, the surface of which has salt of dicarboxylic acid, where dicarboxylic acid contains from 7 to 10 carbon atoms, and dispersive and/or milling agent. Particles of natural mineral solid substrate contain compound of group 2 metal by IUPAC, which is selected from natural milled calcium carbonate, magnesium-calcium carbonate or any of their mixtures. Natural milled carbonate is selected from marble, limestone, chalk or any their mixture, and magnesium-calcium carbonate represents dolomite.EFFECT: composition is an effective beta-nucleation agent, which ensures high impact viscosity of polypropylene.14 cl, 3 tbl, 27 ex |
