The prepared films were investigated by structural, optical and thermal studies. X-ray diffraction (XRD) scans revealed the semicrystalline nature of the blends for lower concentrations of PVA up to 60 wt % and the amorphous nature for higher ones. Fourier transform infra-red spectroscopy (FTIR) of blend samples indicates that there is a compatibility between PVA and MAA:EA copolymers through the formation of hydrogen-bonding between their polar groups.SEM image of polymer blend suggested the presence structural reorganization of polymer chains. UV-Visible spectral analysis revealed that the intensity of the shoulder around 271 nm decreases with increasing MAA:EA content. In DSC analysis, a single glass transition temperature for each blend was observed, which supports the existence of compatibility of such systems. From the observed results, 50:50 (wt %) PVA/MAA:EA is found to be the optimum blending ratio.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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","url":"https://scielo.figshare.com/articles/Structural_Optical_and_Thermal_Characterizations_of_PVA_MAA_EA_Polyblend_Films/6832169/1","contentUrl":null,"metadataVersion":2,"schemaVersion":"http://datacite.org/schema/kernel-4","source":"mds","isActive":true,"state":"findable","reason":null,"viewCount":0,"viewsOverTime":[],"downloadCount":0,"downloads
