The process conditions, structural, thermal, morphological, and mechanical properties were analyzed using Fourier transform infrared spectroscopy, differential scanning calorimetry, scanning electron microscopy, and mechanical testing. Results indicated that PVC/PE and PVC/PP blends were immiscible, while PVC/PMMA blends were miscible. The miscibility directly enhanced the mechanical properties, with yield stress and elastic modulus of PVC/PMMA (95/5 wt%) blends improving by 29.7% and 28.8%, respectively. Calendering conditions, such as banking time and current values, improved by 2-32% for all PVC blends. The increased miscibility significantly reduced energy consumption and production time, offering a cost-effective method for calendering PVC films. https://www.materialsciencejournal.org/vol21no2/enhancing-calendering-process-conditions-by-blending-polyvinyl-chloride-with-polyethylene-polypropylene-and-polymethyl-methacrylate/ Calendering miscibility polymer blend films PVC/PMMA blends
