摘要：

The studies presented explore the effects of homopolymer crystallinity and molecular weight on the surface composition of a homopolymer blend system. Angle-dependent electron spectroscopy for chemical analysis (ESCA or XPS (X-ray photoelectron spectroscopy)), Fourier transform infrared spectroscopy coupled with attenuated total reflectance (ATR-FTIR), and differential scanning calorimetry (DSC) results are presented for miscible and immiscible solvent-case homopolymer blends of poly(epsilon-caprolactone) (PCL) and poly(vinyl chloride) (PVC). From these studies, it was found that the surface composition of a PCL/PVC homopolymer blend is governed by a combination of the homopolymer molecular weight and degree of crystallinity.
