The different properties of carboxymethyl cellulose (CMC)mainly depend upon three factors: molecular weight of the polymer, averagenumber of carboxyl content per anhydroglucoseunit (AGU) and the distribution of carboxyl substituents along the polymerchains. The specific control of the structure and the determination ofsubstituent distribution of CMC are of primary significance for the elucidationof structure-property relationships (necessary to optimize the performance ofthe final product) and for the product quality control. The thermal analysis is a suitable tool to study thecomposition of the polymer. Thermal analysis and testing of polymers across thepolymer supply chain and lifecycle is a powerful means of measuring physicalproperties, transitions, aging processes,the effect of additives and the influence of diverse production conditions onthese materials.

Thermal analysis, such as DSC and TGA are commonlyused to describe the behavior of a sample as a function of temperature. DSC andTGA are capable of revealing thermal transitions, degradation processes, and thermal stability studies. Thermogravimetricanalysis 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 variousprocesses under isothermal or non?isothermalconditions. DSC technique, which is used to study the chemical and physicaltransitions of polymers, during chemical curing, analysis of chemicaldecomposition, glass transition, melting and crystallization phase (physical)and more, all of which being instrumental in gaining invaluable insight intothe materials. Moreover, dielectric investigations are of specialinterest in relation to polymers because they provide detailed information onthe molecular configurations. The methodused in the study for characterizing the CMC can signify a valuable tool forthe quality control in the industrial CMC production, as well as for exploringstructure-property relationships in Carboxymethylcellulose.
