Abstract: | Third-power law type equations of the linear expansion factor αs and of the excluded volume effect h(), expressed by a conventional notation, are derived for a wormlike chain as an extension of the Yamakawa and Stockmayer theory J. chem. Phys.57, 2843(1972)], in which the corresponding fifth-power law type equations were obtained. The literature data on 11 systems of solutions of cellulose and its derivatives are analysed, by using a penetration function method based on the derived equations, to evaluate an excluded volume effect for a wormlike chain model. The results are compared with those deduced for a pearl necklace model. |
