Abstract
Pressed films of binary blends (polyamide with low-density polyethylene or Surlyn) and ternary (polyamide with low-density polyethylene and Surlyn or a graft-copolymer of acrylic acid onto low-density polyethylene) were examined by dynamic mechanical analysis, thermally stimulated current, and small-angle X-ray scattering. The variation of the glass transition temperature for two phases in the blends was studied by dynamic mechanical analysis and thermally stimulated current. X-ray scattering from the relation of the phases was analyzed using Porod's law and led to values of the interface layer in the blends. © 2000 John Wiley & Sons, Inc.
