摘要: Coarsening behavior—optical micrographs of poly(ɛ-caprolactone) (PCL)/ poly(styrene-co-acrylonitrile) (SAN) (70/30) blend prepared by precipitation into methanol, during static annealing at 200 °C: after 1 and 2 min, the regularly phase-separated structure was achieved; 6 min, coarsened to particles approximately 10 μm in size a matrix small domains 1--2 μm appeared both regions; 15 min, grew several tens microns number increased; quenching 25 °C crystallization—the large dispersed can be assigned PCL-rich region.
