Flory dimension
WebSep 7, 2007 · Calculation of the maximal diameter for P5K2 using the Flory dimension for 5-kD PEG gives a molecule with D max ~ 190 Å (i.e., Hb diameter = 70 Å + PEGs, 2 × 60 Å), thus providing an estimation for the mushroom conformation of the PEG chains on P5K2 that fold to ~60% of their full Flory dimensions. http://polymerdatabase.com/polymer%20physics/2PT.html

WebFlory-Fox theory (or Fox-Flory) n. This theory is relates viscosity to molecular dimensions by treating the polymer molecule as a hydrodynamic sphere. In a 0-solvent in which the molecular coU is compact, these authors write the intrinsic viscosity as,... [Pg.421] WebThe size of transition between good-solvent scaling and Gaussian scaling is called the correlation length or the "Blob" size. The persistence length remains unchanged while the overall coil size, as reflected in R g, …
WebA flexible polyanion is more likely to adopt an extended conformation suitable for templating than is a flexible neutral polymer, which is more likely to fold. 21 The Flory dimension of a polyelectrolyte (like DNA), other things being similar, is much larger than that of a biopolymer with, for example, a repeating dipole. 22 As noted above ... WebThe Flory radius, R F, is defined by the random walk law, The Flory radius applies, for the most part, in the melt. When a polymer is put in solution with an organic solvent, such as polystyrene in gasoline, the coil expands to a larger size than the size …
