Abstract
AbstractThe compatibility of polymer blends of high‐molecular‐weight polycarbonate (PC) and high‐molecular‐weight poly(hexamethylene sebacate) (HMS) were characterized. Samples were prepared by solution blending them In methylene chloride followed by doctor blade casting. Optical spectroscopy, tensile stress‐strain, differential scanning calorimetry, and dielectric relaxation spectroscopy were employed to determine the physical and mechanical properties of the blends. These high‐molecular‐weight blends exhibit a limited solubility of HMS In PC as evidenced by a decrease in the glass‐transition temperature of PC. In fact, HMS solubility increases PC mobility sufficiently to allow partial crystallization of PC. Over most of the composition range, HMS phase separates and crystallizes.
