Give reason : Why molecular mass of polymer is always expressed as an average ? |
|
Answer» Solution :Polymer properties are closely related to their molecular mass, size and structure. The growth of the polymer chain during their synthesis is dependent upon the availability of the monomers in the reaction MIXTURE. Thus, the polymer sample contains CHAINS of VARYING lengths and hence its molecular mass is ALWAYS expressed as an AVERAGE. The molecular mass of polymers can be determined by chemical and physical methods. |
