On the application of fourier transform infrared spectroscopy to the elucidation of specific interactions in miscible polyester‐poly(vinyl chloride) blends

Abstract

Abstract FT‐IR spectroscopic studies have been performed in an attempt to elucidate the nature of the specific interactions occurring in miscible poly(ϵ‐caprolactone) (PCL)‐poly (vinyl chloride) (PVC) blends. Studies of low molecular weight analogues, polymer/solvent mixtures and blends of PCL and α‐deuterated PVC are presented. The results strongly suggest that a hydrogen bonding type of interaction between the carbonyl bond of PCL and the α‐hydrogen of PVC exists in compatible PCL‐PVC blends.
