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% by weight, preferably 20 to 60% by weight, of short reinforcing fibers,30 to 100% by weight, preferably 40 to 80% by weight, of a thermoplastic matrix based on at least one semi-crystalline polyamide polymer,0 to 50% of additives and/or other polymers,where said semi-crystalline polyamide polymer is:a) a reactive composition comprising or consisting of at least one reactive polyamide prepolymer precursor of said semi-crystalline polyamide polymer,or in alternative to a),b) a non-reactive composition of at least one polyamide polymer where said composition is that of said thermoplastic matrix defined above,and said reactive polyamide prepolymer for the composition a) and said polyamide polymer for the composition b) comprising or consisting of at least one BACT/XT copolyamide.
