Technical Abstract: Bioblends are polymer blends in which at least one of the components is a biodegradable material derived from natural or synthetic sources. Such blends are important for the development of fully or partially biodegradable and biocompatible materials. However, development of useful blends requires that blend components be compatible. One method of investigating compatibility in polymer blends is to determine the existence or lack of intermolecular interactions between blend components. There are a variety of techniques for probing interactions, each with its own criteria for establishing the presence or absence of intermolecular interactions. In this work, application of thermogravimetric analysis (TGA), modulated differential scanning calorimetry (MDSC), and Fourier transform infrared photoacoustic spectrometry (FTIR-PAS) to probe for interactions in a model binary bioblend will be discussed. The bioblend comprises poly(tetramethyleneadipate-co-terephthalate), also known as Eastar Bio Ultra (EBU), and polystyrene.
