Intrinsic Viscosity, Diffusion, and Sedimentation Rate of Polymers in Solution

摘要: Intrinsic viscosity, diffusion and sedimentation rate of polymers in solution is calculated by a generalization Einstein's theory for impermeable spheres. For the coiled polymer molecule sphere substituted which hinders liquid flow through its interior only to degree depending on average density space solution. The amount shielding introduced this way determines exponent customary exponential relation between intrinsic diffusion, or molecular weight. This shown have merits an interpolation formula. It how dimensions coil can be derived from experimental data these are compared with those interference measurements. point stressed that viscosity weight rather indirect depends essentially type unde...
