SEMI-CRYSTALLINE POLYAMIDE COMPOSITION HAVING A HIGH GLASS TRANSITION TEMPERATURE AND A HIGH MELTING TEMPERATURE FOR A THERMOPLASTIC MATERIAL, PRODUCTION METHOD THEREOF AND USES OF SAME

摘要

The invention relates to a composition for a thermoplastic material, comprising: - 0 to 70 wt.-%, preferably 20 to 60 wt.-%, short reinforcing fibres, - 30 to 100 wt.-%, preferably 40 to 80 wt.-%, a thermoplastic matrix based on at least one semi-crystalline polyamide polymer, - 0 to 50 wt.-% additives and/or other polymers, said semi-crystalline polyamide polymer being: a) a reactive composition comprising or consisting of at least one reactive polyamide prepolymer precursor of the semi-crystalline polyamide polymer, or, as an alternative to a), b) a non-reactive composition of at least one polyamide polymer, the composition being that of the thermoplastic matrix defined above, and the reactive polyamide prepolymer of the composition a) and the polyamide polymer of the composition b) comprising or consisting of at least one BACT/XT copolyamide.
