Interactions in Miscible Polymer Blends.
Abstract
This research has been concerned with learning more about the energetic interactions between the segments of polymers and how they affect the phase behavior and the physical properties of polymer blends. A primary tool for quantitative investigation of these interactions has been the calorimetric measurement of heats of mixing between low molecular weight liquids having structures similar to those of polymers of interest. In this way, it has been possible to simulate both intermolecular and intramolecular interactions that are important in blend phase behavior and properties. Various theories have been employed to utilize this information including one that permits prediction of miscibility by a group contribution method. Several new miscible blend systems were identified, e.g. polycarbonate/poly(methyl methacrylate), and several ways to use copolymerization to manipulate phase behavior were demonstrated. Keywords: Polymer blends, Copolymers, Permeation, Miscibility, Calorimetry, Spectroscopy, Sorption, Rubber toughening, Liquid crystalline polymer, Polycarbonates, Methacrylates, Acrylates, Styrenics, Adhesion.
