发明名称 Granulate composition of antiblocking agents and additives for polymer production
摘要 The invention comprises a granulate comprising a) a micronized silicic acid gel (A) with an average particle size from 2 to 15 microns, a specific pore volume from 0.3 to 2.0 ml/g, a specific surface (BET) from 200 to 1000 m2/g, in a concentration from 5 to 60% by weight or b) a hydrated or dehydrated aluminosilicate (B) which contains sodium and/or potassium and/or calcium cations, with a particle size between 1 and 25 microns in a concentration from 5 to 75% by weight and c) an organic additive composition (C) in a concentration from 25 to 95% by weight, but at least 5% more (measured by the oil adsorption process) than that which is necessary to fill all pores of the silicic acid and the spaces between the silicic acid particles and the aluminosilicate and the aluminosilicate particles.
