Solution properties of ultrahigh-molecular-weight polymers, 16. Unperturbed dimensions of poly(isobutyl methacrylate)

Three techniques, i. e., the Lenka extrapolation method, the Stockmayer‐Fixman method, and the extrapolation of the Mark‐Houwink constants to a = 0,5 were applied to determine the unperturbed dimensions of ultrahigh‐molecular‐weight poly(isobutyl methacrylate). A correction term, depending on the ex...

Zusammenfassung:Three techniques, i. e., the Lenka extrapolation method, the Stockmayer‐Fixman method, and the extrapolation of the Mark‐Houwink constants to a = 0,5 were applied to determine the unperturbed dimensions of ultrahigh‐molecular‐weight poly(isobutyl methacrylate). A correction term, depending on the exponent a of the Mark‐Houwink relation, is suggested to be introduced into the Stockmayer‐Fixman‐Burchard equation.
