摘 要: 利用FTIR、X-射线衍射、GPC、GC和化学分析手段研究了经PPM活化剂处理前后棉纤维素的变化.结果表明,经活化处理后无定形区的纤维素发生了部分氧化降解,而结晶区的纤维素没有变化。 Changes of cotten cellulose before and after being treated were investignted by means of FTR, X-Ray, GPC, GC and chemical analysis methods. The results showed that cellulose in amorphous regions is oxidatively degraded during the activating treatment, but that in crystalline regions has no Changes.
