The use of a polyamide molding compound with a high melt stiffness to the coextrusion with a high-melting polymer

摘要

In the case of use of a moulding compound which contains the following components:a) 100 w - parts of polyamide, as well asb) 0,005 to 10 w - parts of a compound having at least two carbonate unitsfor coextrusion with a molding compound on the basis of a high-melting polymers, which has a crystallite melting point t_m of at least 270°C. and / or a glass transition temperature t_g of at least 190°C. a composite structures with good quality are obtained, in particular with good layer - and poor wall thickness distributions.
