Poly(L-lactic acid) (PLLA) was blended with an ethylene-vinyl acetate (EVA) copolymer, which is generally recognized as a phase-separated system. The interactions between these polymer species were examined via spherulite observation. PLLA/EVA blend concluded to be partially miscible onset temperature for the crystallization of PLLA, crystalline polymer, systematically changed when PLLA EVA at various ratios. glass transition behavior almost absent in thermogram PLLA:EVA ratio greater than 2:1. size distribution became finer from 3:1 2:1 1:1, and observing spherulites difficult 1:2. Because nucleation position different each time during repeated melting/crystallization spherulites, this system exhibited homogeneous nucleation. In addition, plot versus time, inclination angle = blends, critical estimated.
