    摘要： The invention relates to an article based on a mixture of polyamide and polyolefin, which article includes at least one weld line due to multi-port injection molding, said article characterized in that the ratio of the viscosities of the polyolefin to the polyamide, measured at a shear rate higher than 100 s−1, is greater than 0.70, and that the quantity of polyamide is sufficient for the elongation at break to be greater than 10%. A typical application is the production of an injection molded automobile fender.
