This research paper explores the morphology of PVC/PE mixtures and investigates the effects of compatibilizers and mixing conditions on particle size and distribution. The study reveals that the addition of chlorinated polyethylene or graft copolymers of PVC with PE leads to smaller particle sizes and improved dispersion of the dispersed phase. These findings demonstrate the importance of compatibilizers in achieving a desirable morphology. The research also highlights the differences in morphology development between PVC-matrix and PE-matrix mixtures. In PVC-matrix blends, the compatibilizer and higher mixing speeds result in finer dispersion and uniform distribution of PE particles. Conversely, PE-matrix mixtures exhibit distinct separation into finely dispersed areas and regions with aggregated PVC particles. Overall, the study provides valuable insights into optimizing the morphology of PVC/PE mixtures, leading to improved properties. It sets the groundwork for future research on enhancing deformation characteristics through phase separation synergy and crosslinking of the PE matrix.
