Abstract
The rotational isomeric state (RIS) model was used to calculate the mo lecular dimensions of poly(ethylene isophthalate) (PEI) and poly(ethyl ene naphthalene-2,6-dicarboxylate) (PEN) by introducing new descriptio n for aromatic segments and by adopting the statistical weight paramet ers of PET. The mean square dimension ratios ((<r(2)>(0)/M)(infinity)) of PEN and PEI were 0.653 and 1.167, respectively, and the entangleme nt molecular weight (M-e) of PEI and PEN were 1850 and 1810, respectiv ely.
