摘要: A polypropylene film which has a crystallite size of not more than 12.2 nm, the crystallite size being determined using Scherrer's equation from a full width at half maximum of the reflection peak from (040) plane of α crystal measured by a wide-angle X-ray diffraction method, and a volume resistivity of not lower than 6×1014 Ω·cm, the volume resistivity being calculated in accordance with equation I from a current value that is measured 1 minute after applying a voltage at a potential gradient of 200 V/μm in an environment at 100° C. Equation I: volume resistivity=[(effective electrode area)×(applied voltage)]/[(polypropylene film thickness)×(current value)].

摘要: The present invention provides a method for producing pentosan polysulfate, the method including a first step of obtaining an acidic xylooligosaccharide from a plant-derived raw material, and a second step of obtaining pentosan polysulfate from the acidic xylooligosaccharide. The first step includes a step of depolymerizing the plant-derived raw material. The second step includes a step of sulfating the acidic xylooligosaccharide. The method further includes a deacetylation step of adding a base to achieve a pH of 11 or higher. The deacetylation step is a step performed after the depolymerization step. The production method of the present invention can provide pentosan polysulfate having a low acetyl group content, and also produce pentosan polysulfate with a high yield inexpensively and efficiently.
