Melt blends of polycarbonate and poly(ethy1ene terephthalate) were prepared and examined for their transitional behavior by thermal analysis and dynamic mechanical testing. A single T, was observed for compositions containing more than 6%70% P E T by weight while compositions below this range showed

## Abstract Polycarbonate blends with poly(ε‐caprolactone) were prepared by both melt‐blending and solution‐blending techniques, and the properties of these blends were studied by thermal analytical and dynamic mechanical testing methods. Each blend composition was found to have a single glass tran
