SHORT DIAMINE-BASED SEMI-CRYSTALLINE POLYAMIDE COMPOSITION HAVING A HIGH GLASS TRANSITION 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 1000% 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,said semi-crystalline polyamide polymer being:a) a reactive composition comprising or consisting of at least one reactive precursor polyamide prepolymer of said semi-crystalline polyamide polymer,or as an alternative to a),b) a non-reactive composition of at least one polyamide polymer, said composition being that of the thermoplastic matrix defined above,and said reactive polyamide prepolymer of composition a) and said polyamide polymer of composition b) comprising or consisting of at least one BACT/XT copolyamide.
