Key Points

To examine the compatibility, morphological structures, and mechanical behavior of poly-ε-caprolactone blended with poly(vinyl chloride), nitrocellulose, and cellulose acetate butyrate across various compositions.
Blended poly-ε-caprolactone (PCL) with poly(vinyl chloride) (PVC), nitrocellulose, and cellulose acetate butyrate at multiple concentration ratios.
Characterized blend properties using differential scanning calorimetry, dynamic mechanical testing, small-angle light scattering, light microscopy, and stress–strain testing.
PCL blended with PVC showed compatibility across all proportions, crystallizing as negative spherulites in the 40–100% PCL range that remained volume-filling at up to 35% PVC.
Nitrocellulose blends exhibited compatible glass transition behavior at 50–100% PCL with rod-like crystalline structures, but phase-separated at concentrations below 50% PCL.
Cellulose acetate butyrate blends were phase-separated across compositions, while stress–strain analysis confirmed PCL functioned as an effective plasticizer across all evaluated polymer systems.
