The Optical, Structural and Thermal Properties of Transparent Poly (Methylmethacrylate)/Cellulose Acetate Phthalate Blend
Miscible transparent blend consist of poly (methylmethacrylate) with cellulose acetate phthalate was prepared in order to get more transparent blend for ultraviolet rays. The blend was prepared by melt-blending and examined using UV-VIS spectroscopy. The structural, mechanical and thermal properties of selected samples were studied using X-ray diffraction, scanning electron microscopy, dynamic mechanical analysis, and thermos-gravimetric analysis. The UV-VIS spectrum exhibited the best blend ratio which has low absorbency to ultraviolet rays, On the other hand, high optical transparency within visible region. The results also showed that the blend has an amorphous structure as X-ray diffraction diffractogram. Moreover, thermal stability happened with the presence of cellulose acetate phthalate in the blend.
