WebJan 24, 2024 · Polymer properties are closely related to their molecular mass, size and structure. The growth of the polymer chain during their synthesis is dependent upon the availability of the monomers in the reaction mixture. Thus, the polymer sample contains chains of varying lengths and hence its molecular mass is always expressed as an average.

WebMar 20, 2009 · The intrinsic viscosities can be represented by the Mark–Houwink–Sakurada equation, which can be written for the theta solvent as (1) [ η] θ = K θ M 1 / 2 and for any solvent quality in the form (2) [ η] = K η M a.

WebMay 10, 2005 · The refractive index of the condensed globule structure is higher than that of the random coil polymer. Figure 3 shows the intensity size distributions obtained at (a) 10°C and (b) 40°C. When the PNIPAM molecules are in a random coil configuration, the size distribution is broader compared to when the polymer is in a condensed globule.

WebAs more solvent is added, the range of sizes where good solvent scaling is observed increases until a dilute condition is reached. As with the thermal blob, the concentration blob can be used to calculate the size of a polymer coil, R F = x n x 1/2.
