What is Characterization of the differences in the crystallinity from surface to bulk of compression-molded polypropene sheets using attenuated total reflection fourier-transform IR spectroscopy about?
## Abstract The crystallinities of compression‐molded polypropene sheets were investigated by applying Fourier‐transform (FT)‐IR and attenuated total reflection (ATR) FT‐IR analyses. Two internal reflection elements, Ge and KRS‐5, with an angle of incidence of 45°, were used to obtain the depth profiles of the crystallinity of polypropene sheets from the surface to bulk. The crystallinity in the region from the surface to about 0,7 μm depth was considerably lower than that in bulk. Polypropene sheets with higher comonomer content showed the same tendency, which was enhanced with decreasing molding temperature.
