MOLDING COMPOSITION WITH GOOD CAPABILITY FOR BLOW MOLDING

摘要

A molding composition imposed of at least 50% by weight of a polyamine-polyamide copolymer which is prepared using from 0.05 to 2.5% by weight of a polyamine having at least 4 nitrogen atoms and which has a viscosity of at least 5 000 Pa~s at 250.degree.C and at a shear rate o f 0.1 1/s, and which has a viscosity ratio of at least 7 at 250.degree.C, when the melt viscosities at shear rates of 0.1 1/s and 100 1/s are compared with one another, has high melt stiffness and is easy to cut, and performs well in blow molding.
