Relation of Chain Constitution with Phase Structrue in Blends: Compatibility of Two Phases in Blends of Polyamide with Low-Density Polyethylene and Its lonomers

摘要

Pressed films of binary blends (polyamide with low-density polyethylene or Surlyn) and terary (polyamide with low-density polyethylene and Surlyn or a graftcopolymer 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 teh interface layer in the blends.
