ABSTRACT:
The present invention relates to a composition comprising at least two incompatible thermoplastic polymers and at least one compatibilizer, to a method of preparing this composition, and to the use of said composition for the manufacture of thermoplastic articles or semi-finished products having, in particular, improved mechanical properties. A composition according to the invention is such that said polymeric compatibilizer includes at least two groups of polar and apolar units compatible with the respectively polymers, and it is characterized in that it comprises the product of a hot compounding reaction, in the presence of a crosslinking system, of said compatibilizer in the crosslinkable state with said thermoplastic polymers, in such a way that only said compatibilizer is crosslinked in said composition.
