Short diamine-based semi-crystalline polyamide composition having high glass transition temperature for thermoplastic material, method for producing the same and use thereof

摘要

The present invention is based on -0 to 70% by weight, preferably 20 to 60% by weight of reinforcing staple fibers, -30 to 100% by weight, preferably 40 to 80% by weight of at least one semicrystalline polyamide polymer. A composition for a thermoplastic material comprising a thermoplastic matrix, 0 to 50% by weight of additives and / or other polymers, said semicrystalline polyamide polymer comprising: a) said semicrystalline polyamide polymer At least one reactive composition comprising or consisting of at least one reactive precursor polyamide prepolymer, or as an alternative to a), b) a composition of the thermoplastic matrix as defined above, A non-reactive composition of a polyamide polymer, said reactive polyamide prepolymer of composition a) and said polyamide of composition b). Rimmer is, it contains at least one BACT / XT copolyamide, or consists of, to compositions. [Selection diagram] None
