Paper doi abstract bibtex Microstructure-dependent changes in the crystalline properties of poly(ethylene-co-vinyl acetate) (EVA) was investigated using various EVAs at different VA contents via X-ray diffraction (XRD). The parameters analyzed herein were percentage crystallinity (X$_{\textrm{c}}$), interplanar crystal spacing (d$_{\textrm{hkl}}$), crystal stack size (D$_{\textrm{hkl}}$), and the number of crystal plane piles (N$_{\textrm{hkl}}$). The X$_{\textrm{c}}$s of [110] and [200] crystals were 21.0-4.1 and 6.7-1.4%, respectively, and they decreased by approximately 2.3 and 0.7% for every mol% of the VA content, respectively. The X$_{\textrm{c}}$ ratios of the [110] and [200] crystals were approximately 3. The d$_{\textrm{110}}$s and d$_{\textrm{200}}$s values were 0.41-0.42 and 0.37-0.38 nm, respectively. The D$_{\textrm{110}}$s and D$_{\textrm{200}}$s values were 9.56 -21.92 and 7.00-16.42 nm, respectively. The d$_{\textrm{hkl}}$s increased with an increase in the VA content, whereas the D$_{\textrm{hkls}}$ decreased. The N$_{\textrm{110}}$s and N$_{\textrm{200}}$s were 22.7-51.3 and 18.3-43.2, respectively, and they decreased by increasing the VA content. EVA with the same VA content showed different crystalline properties as per the suppliers, and some EVAs deviated from the average trends. This could be explained by the difference in their microstructures such as the sizes and distribution uniformity of the ethylene sequences in EVA chains.
