Summary

A simple model based only on steric constrictions of chain molecules is used to describe the conformational characteristics of polymer chains endowed with various degrees of rigidity. The effect of rigidity of bond rotations was studied in terms of the model in relation to chain molecule size; a rigidity criterion was thus obtained, based on the width of the interval of rotational angles. Other results suggested the scaling law between the size of the chain and the number of monomers to become modified with the degree of chain rigidity. Examples of scaling behavior are discussed. An additional parameter, helicity, which corresponds with the average rotation angle, is presented as helpful in understanding the structural characteristics of polymer chains.
Keywords: rigidity of polymer chains, conformational characteristics, scaling law, helicity
