Patent

CA 2633193

The invention relates to polycarbonate compositions comprising laminar silicates which are modified with organic polymers by means of a solvent-free melt process, and to a process for their preparation. The resulting moulding compositions have an improved heat stability and a relatively low maximum rate of decomposition in the event of fire.

L'invention concerne des compositions à base de polycarbonate comprenant un silicate stratifié, lesdites compositions étant modifiées par des polymères organiques par un procédé utilisant une masse fondue sans solvant, ainsi qu'un procédé de fabrication desdites compositions. Les masses de moulage obtenues présentent une meilleure stabilité thermique et une vitesse de décomposition maximale moindre en cas d'incendie.
