Abstract

This paper suggests a viscoelastic method to analyze microscopic structure of polymer blends which could be characterized by DMA and TEM. The viscoelastic method is to use weighted relaxation spectrum. We used poly(lactic acid)/poly(butylene adipate-co-terephthalate) and poly(lactic acid)/poly(vinyl acetate) blends in order to check the validity of the viscoelastic method. The former is an immiscible blend and the latter is a miscible blend.
