    • The invention relates to thermoplastic compositions comprising a polymer matrix and an additive which modifies the rheological behaviour 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 functionalised 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 moulding, extrusion, engineered plastics, wires and fibres.
    • 本发明涉及包含聚合物基质和添加剂的热塑性组合物,其改变熔融状态下的基质的流变行为。 本发明的目的是提供一种优选的非反应性添加剂,其可以分散在基质中,并且可用于在流变性/机械性能方面获得良好的折中。 根据本发明,添加剂是由R 2基团官能化的超支化聚合物,R 2是下列类型的基团:硅型,直链或支链烷基的取代或未取代的烃, 芳基,芳烷基,烷基芳基或脂环族,其可以包含一个或多个不饱和基团和/或一个或多个杂原子。 优选地,组合物不含有超支化聚合物,其在其中产生相对于包含基质M但不含超支化聚合物添加剂的样品组合物大于或等于7%的基质M的摩尔质量的降低 )。 所述质量测量优选使用预定方案P.本发明适用于模制,挤出,工程塑料,线和纤维。
