Thermoplastic polymer mixture with improved mechanical properties

摘要

A thermoplastic polymer composition contains at least two distinct polymers, characterized in that it comprises at least one polymer P1 containing at least one reactive function and at least one modified polyolefin P2 containing at least one succinimide ring substituted on the nitrogen by a reactive group, the ring being carried either by the main chain or by a side chain, and optionally at least one third polymer P3 selected from the group formed by polymers and copolymers obtained by polymerisation of one or more olefinic compounds. A mixture of polymers comprises at least one composition as defined above and at least one other polymer P5 which is identical to or different from polymer P3 and optionally at least one other polymer P6 which is identical to or different from polymer P1.
