摘要:

AbstractThe relationship [η] =KMaand unperturbed dimensions of the copolyesters poly(ethylene terephthalate‐co‐ethylene isophthalate) with 7.5% and 25% isophthalic structures in the main chain were determined. The experimental data proved the influence of the amount of isophthalic structures upon the values ofKandafrom the relation between intrinsic viscosity and molecular weight and on the values for unperturbed dimens
