Notizen:
The 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.
