<p>The dispersion comprises a polymer carrier, which is polypropylene in an amount from 68.0 to 88.0% by weight., inorganic additives in an amount of from 10.0 to 20.0% by weight., which consisting of anatase and rutile TiO2 crystal modification of primary particle size from 14 to 30 nm and powder dispersant based polyethylene wax and / or polypropylene wax or a polyolefin with a molecular weight of less than 40 000 g / mol in an amount of 2.0 and 12,0% by weight. It describes also a method of preparing the dispersion which is used to prepare moldings and fine polypropylene fibers.</p> |
