Fremgangsmåte for behandling av et metallfyllstoff med et polydialkylsiloksan og en fettsyre, de resulterende hydrofobe fyllstoffer samtderes anvendelse ipolymerer for pustende filmer

摘要

The invention relates to a method for treating a mineral filler by means of a polydialkylsiloxane and a fatty acid, the hydrophobic fillers thus obtained, and the application thereof in polymers for the manufacture of films and notably "breathable" films.
