Abstract
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.
