摘要:
The invention relates to thermoplastic compositions comprising a thermoplastic polyamide matrix and at least one additive which modifies the interaction between the matrix and an agent. The purpose of the invention is to provide an additive which modifies the interaction between a copolyamide-type thermoplastic copolyamide matrix and at least one agent. The aforementioned additive, which comprises at least one hyperbranched functionalised polymer, is not compatible with the matrix. Moreover, said additive can be used for the controlled modification of the interaction between the thermoplastic copolyamide and an internal or external chemical agent. Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7% in relation to a sample composition which comprises matrix M but does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a determined protocol P. The invention is suitable for use in moulding, injection moulding, injection/blow moulding, extrusion/blow moulding, extrusion or spinning.

The invention relates to thermoplastic compositions comprising a polymer matrix and an additive which modifies the rheological behavior of the matrix in the molten state. The purpose of the invention is to provide a preferably non-reactive additive which can be dispersed in the matrix and which can be used to obtain a good compromise in terms of rheological properties/mechanical properties. According to the invention, the additive is a hyperbranched polymer which is functionalized by R radicals, R being a radical of the following type: substituted or non-substituted hydrocarbon, of the silicon type, linear or branched alkyl, aromatic, arylalkyl, alkylaryl or cycloaliphatic, which can comprise one or more unsaturations and/or one or more heteroatoms. Preferably, the composition does not contain hyperbranched polymers which produce therein a reduction in the molar mass of matrix M which is greater than or equal to 7% in relation to a sample composition which comprises matrix M but which does not contain hyperbranched polymer additive(s). Said mass measurement is taken preferably using a predetermined protocol P. The invention is suitable for molding, extrusion, engineered plastics, wires and fibers.
