Polyamide-based thermoplastic polymer compositions that exhibit a good balance among the properties thereof, in particular their mechanical properties, and a high fluidity in the molten state; such compositions contain at least one high-fluidity polyamide and a shock modification agent having functional groups that react with the polyimide.

Polyamide-based thermoplastic polymer compositions

The invention relates to a thermoplastic polymer composition that contains polyamide and comprises an excellent compromise of properties, in particular mechanical properties, and a high fluidity at the molten state. The invention particularly relates to a composition containing at least a high-fluidity linear polyamide and optionally fillers such as glass fibers, and to a method for making such a composition.

Thermoplastic polymer composition containing polyamide

The invention concerns a thermoplastic copolyamide and composition comprising as matrix said thermoplastic copolyamide, and a method of making such thermoplastic copolyamide. More particularly it concerns a copolyamide of the statistical tree type resulting from the reaction between a plurifunctional monomer comprising at least three reactive functions to form an amide function, said functions being two different types, and bifunctional monomer conventionally used in making linear polyamides. The resulting copolyamide has a very low softness index in molten state compared to the linear polyamide and improved shock-resistant properties. The invention also concerns with methods for making these copolyamides and composition for molding, extruding or injecting parts. Said compositions comprise fillers and additives and said copolyamide as a matrix.
