Blends of hyperbranched poly(ether amide)s and polyamide-6

Blends of polyamide-6 PA6 as matrix and a hyperbranched poly(ether amide) P 1, based on 2-(3,5-dihydroxyphenyl)-1,3-oxazoline, were prepared. The conte nt of the hyperbranched polymer was varied between 0.1 and 10 wt.-%. The bl ends were prepared in order to investigate the influence of the hyperbranch ed material on the rheological behavior of the new material. The mixed syst ems exhibit a homogeneous morphology even at high concentrations of the pol y(ether amide). The complex viscosity of the new materials was reduced alre ady at a small amount of the hyperbranched polymer whereas the mechanical p roperties of the blends remained nearly constant compared to the pure PA6.
