FIELD: chemistry.SUBSTANCE: invention relates to a polypropylene polymer composition which contains phenol antioxidants and use of talc with an organometallic coating in polymer compositions. The polymer composition contains: (a) at least 50 wt % polypropylene; (b) 10000-400000 ppm coated talc; (c) 100-5000 ppm phenol antioxidants, and (d) optionally 100-5000 ppm phosphorus-containing antioxidants. The coated talc is used in the polypropylene composition to provide emission of volatile compounds from the product, measured according to VDA 277 standards, (a) all volatile compounds of the polymer composition in total amount of 120 mcg/g or less and/or (b) 2-methyl-propene of said polymer composition in amount of not more than 70 mcg/g.EFFECT: obtaining a polypropylene polymer composition which contains phenol antioxidants.14 cl, 1 tbl, 1 ex |
