精制棉制备聚阴离子纤维素工艺研究

STUDY ON THE TECHNOLOGICAL PROCESS OF POLYNIONIC CELLULOSES USING REFINING COTTON AS RAW MATERIAL

采用精制棉经过碱化、醚化得到高取代度且取代基均匀分布的聚阴离子纤维素产品。对制备工艺中的影响因素进行了分析讨论。

Polynionic celluloses were preparated by alkalify and etherify of refining cotton. The degree of replacement of the polynionic cellulosesis was high. The radicals of replacement were distributed evenly. The factors of affection in the technological process of polynionic celluloses were discussed.
