Elongated Rigid or Semirigid Macromolecules

Storage and loss moduli of a 2% solution of poly(7-benzyl-L-glutamate) (molecular weight 345,000) in w-methoxyphenol (a hclicogenie solvent) reduced to 25°C. Pips denote individual temperatures of measurement (—0.1°, 25.0°, 49.9°). Solid curves represent Kirkwood-Auer theory (cf. equations 8 and 9 of Chapter 9). (Tschoegl and Ferry. ) 

Relaxation spectrum of aqueous deoxyribonucleic acid (sodium salt), concentration 0.012 g/ml reduced to 25°C. Points top black, calculated from G bottom black, from tj. (Helders, Ferry, Markovitz, and Zapas. )
