The linear rheological properties of networks formed by adding bis-Pd(II)
cross-linkers to poly(4-vinylpyridine) (PVP) solution are examined, and the scaling law
relationships between the zero shear viscosity (η0) of the networks versus the
concentration of PVP solution (CPVP), the concentration of cross-linkers (CX), and
the number density of elastically active chains (νphantom) are experimentally determined.
The scaling law relationships are compared to the theoretical expectations of the sticky
Rouse and sticky reptation models [Macromolecules 2001, 34, 10581068], and both
qualitative and quantitative differences are observed.
