Determination of the heterogeneity of poly-p-phenylene terephthalamide solutions in sulfuric acid from the turbidity spectrum

Thermodynamics of Systems Containing Flexible-Chain Polymers

“…Previously (Peterlin, 1955;Ptitsyn, 1957), the expression for the scattering form factor has been a generalization of Debye's formula and, in the notation accepted here, has the The matter is that these papers suggested the same swelling law for the internal parts of a macromolecule and for its ends. According to Equations 150 and 167, the internal swelling is stronger.…”
