Abstract

A novel use of the process of physical aging has been employed to help distinguish whether the two components of a polymer blend are miscible or immiscible. This approach appears to be particularly useful in the special case where the glass transition temperature of the two respective blend components are relatively close, i.e. 10 to 20°C. This novel approach is demonstrated through the use of blends of racemic polylactide with the optically active L form of the same species. Different molecular weights and their blends were utilized in this study.
