Abstract

Telah dibuat polipaduan PVC-PMMA pada suhu 170°C dengan variasi komposisi 100/0, 90/10, 80/20, dan 70/30 menggunakan Rheomix. Seng stearat ditambahkan ke dalam polipaduan dengan variasi komposisi 0%, 0,5%, 1%, dan 1,5%. Pengaruh penambahan seng stearat terhadap misibilitas polipaduan dapat dianalisis dari hasil uji mekanik dan penampakan fisik film polipaduan. Penampakan fisik film polipaduan yang bening menunjukkan bahwa film polipaduan tersebut misibel pada setiap variasi komposisi. Penambahan seng stearat tidak berpengaruh terhadap peningkatan misibilitas polipaduan PVC-PMMA. Hasil uji mekanik memperkuat bahwa nilai kekuatan tarik terbesar terdapat pada polipaduan PVC-PMMA dengan persentase penambahan 0%, diikuti 0,5%. Namun, nilai perpanjangan putus terbesar terdapat pada persentase penambahan seng stearat 0,5%.

Poly(vinyl chloride) (PVC)/poly(methyl methacrylate) (PMMA) blends were prepared at a temperature of 170°C with composition variations of 100/0, 90/10, 80/20, and 70/30 using a Rheomix. Zinc stearate was added to the PVC/PMMA blends at concentrations of 0%, 0.5%, 1%, and 1.5%. The effect of zinc stearate addition on the miscibility of PVC/PMMA blends can be analyzed based on the results of mechanical tests and the physical appearance of the blend films. The transparent appearance of the PVC/PMMA blend films indicates that the blends are miscible at each composition variation. The addition of zinc stearate does not improve the miscibility of PVC/PMMA blends. The mechanical test results further confirm that the highest tensile strength is obtained in PVC/PMMA blends with 0% zinc stearate addition, followed by 0.5%. However, the highest elongation at break is obtained with a zinc stearate concentration of 0.5%.
