The invention relates to flame-resistant polycarbonate moulding materials modified with graft polymers, containing phosphorus compounds and specially prepared fluorinated polyolefins. Said moulding materials are characterized by excellent flame resistance and very good mechanical properties such as impact strength and ultimate elongation as well as very high stress-crack resistance.
La présente invention a pour objet des compositions de moulage ignifuges à base de polycarbonate modifié à l'aide de polymères greffés, qui contiennent des composés phosphorés et des polyoléfines fluorées spécialement préparées. Lesdites compositions exhibent d'excellents propriétés d'ignifugation, de très bonnes propriétés mécaniques, telles que la résistance aux chocs après entaille, l'élongation à la rupture, ainsi qu'une très bonne résistance au fendillement sous contrainte.
