BLEND OF POLYMERS HAVING YIELD STRESS AND USE THEREOF FOR THE MANUFACTURE OF METAL-POLYMER COMPOSITES

摘要

The invention relates to a two-phase polymer blend, comprising: (a) a polyamide having a melting point at most equal to 210°C, (b) a polyolefin modified by grafting of carboxyl functions, the rheological behaviour of which in the melt state is characterized by the existence of a yield stress, and also to a process for the preparation thereof. The invention furthermore relates to the use of this polymer blend for the manufacture of composite structures and facings and also the resulting composite structures and facings.
