The effect of varying wt % ratio of PMMA:PCTFE polyblends on its surface morphology and structure has been reported. The value of intermediate glass transition temperature of the blend shows a homogeneous blending of the two polymers. The scanning electron micrographs also confirm the homogeneous blending of the two polymers for very low concentration of polychlorotrifluoro ethyelene (PCTFE) in polymethyl methacrylate (PMMA) matrix. The role of PCTFE as plasticizer is confirmed by the decreasing glass transition temperature of the polyblend material with increasing concentration of PCTFE in PMMA matrix. At and after 5 wt % of PCTFE the blend shows heterogeneous surface morphology. Crystallinity of the blends is found to decrease with increasing PCTFE, concentration. X-ray diffractograms and SEM micrographs also show great amount of heterogeneity of the two constituents of PMMA:PCTFE polyblend at
95:5 wt% composition ratio. Appreciable blending and fascinating set of properties are found to be for lower wt% ratio of PCTFE in PMMA matrix.
