  7. 15. New Mass Spectrometric Methods for Structure Analysis of Carboxymethyl Cellulose

    Författare :Jonas Enebro; Sigbritt Karlsson; Dane Momcilovic; Ulf Germgård; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carboxymethyl cellulose; substituent distribution; rheology; enzyme hydrolysis; cellulase; permethylation; liquid chromatography; MALDI; ESI; mass spectrometry; Polymer chemistry; Polymerkemi;

    Sammanfattning : Carboxymethyl cellulose (CMC) is a cellulose derivative, made from cellulose by introduction of carboxymethyl groups along the molecules. The properties of CMC are affected by several parameters where the molar mass and molar mass distribution, degree of substitution (DS) and the distribution pattern along, and between, the cellulose molecules are the most prominent.
