The and the distribution of carboxyl substituents along the

The different properties of carboxymethyl
cellulose (CMC) primarily depend upon three factors: molecular weight of the
polymer, average number of carboxyl content per anhydroglucose
unit, and the distribution of carboxyl substituents along the polymer chains.
The specific control of the structure and the determination of substituent
distribution of CMC are of primary significance for the elucidation of
structure-property relationships (necessary to optimize the performance of the
final product) and for the product quality control. The thermal analysis
is a suitable tool to study the composition of the polymer. Thermal analysis
and testing of polymers across the polymer supply chain and lifecycle is a
powerful means of measuring physical properties, transitions, ageing processes, the effect of additives and
the influence of diverse production conditions on these materials. Thermal analysis, such as DSC and TGA are commonly
used to describe the behavior of a sample as a function of temperature. DSC and
TGA are capable of revealing thermal transitions, degradation processes, and thermal stability studies. Thermogravimetric
analysis plays an imperative role in determining the thermal stability of the materials. Thermogravimetric
analysis (TGA) is widely used because they provide a rapid quantitative determination of various processes under
isothermal or non?isothermal
conditions. DSC technique, which is used to examine the chemical and physical
transitions of polymers, during chemical curing, analysis of chemical
decomposition, glass transition, melting and crystallization phase (physical)
and more, all of which being instrumental in gaining invaluable insight into
the materials. Moreover, dielectric
investigations are of special interest in relation to polymers because they
provide detailed information on the molecular configurations. The method used in the study for characterizing
the CMC can signify a valuable tool for the quality control in the industrial
CMC production, as well as for exploring structure-property relationships in Carboxymethylcellulose.  Such techniques are used to extract the
insight that needs to more fully
understand the polymer.
