Polymers have many types of structures that cannot be simply expressed by the chemical formulas, e.g. molecular weight and its distribution, stereoregularity, monomer sequence, branched structure, chain stiffness, helicity and so on. Various techniques are used to determine these structures. Such studies are called “characterization”.

摘要

Polymers have many types of structures that cannot be simply expressed by the chemical formulas, e.g. molecular weight and its distribution, stereoregularity, monomer sequence, branched structure, chain stiffness, helicity and so on. Various techniques are used to determine these structures. Such studies are called “characterization”.
