Polymers Large molecules classification

In addition to the classification of liquid chromatographic enantioseparation methods by technical description, these methods could further be classified according to the chemical structure of the diverse CSPs. The chiral selector moiety varies from large molecules, based on natural or synthetic polymers in which the chirality may be based on chiral subunits (monomers) or intrinsically on the total structure (e.g., helicity or chiral cavity), to low molecular weight molecules which are irreversibly and/or covalently bound to a rigid hard matrix, most often silica gel. 

The classification of a condensation polymer Is historically based on the observation that during polymerization a small molecule, such as water, is condensed or removed as part of the reaction. There are a large number of polymers produced from condensation reactions and only a representative sample is presented in... 

The arrangement of the covalent structure in space leads to a convenient method of classification that helps explain polymer properties. Basically there are two such arrangements. The polymer may be present as single molecules, albeit of large individual size (i.e., molecular weight of 10 ), or as an infinite network. The distinction is important because only the separate molecules can exhibit plastic flow and solubility.
