IR Spectroscopic Analysis of the Supramolecular Structure of a Polyvinylidene-Based Polymer System

Abstract

Abstract: An FTIR spectroscopic analysis is performed of the supramolecular structure of blends of polyvinylidene fluoride and polyvinyl butyral in compositions of different percentages. Temperature dependences are obtained for the characteristic intensity of the IR corresponding to ordered and disordered polyvinylidene fluoride in blends with polyvinyl butyral. Breaks in the intensity–temperature dependences for the IR band of ordered polyvinylidene fluoride characterize the glass transitions in the blends.
