Viscoelastic properties of poly(2-vinylpyridine) (P2VP) over a wide range of molecular weight (M) were studied in bulk and solution. It was found that the absolute values of zero-shear viscosity η0 of P2VP in bulk and in α-chloronaphtharene (αCN) are practically the same as those of polystyrene (PS) over whole experimental range of M. The temperature dependence of η0 in bulk is also the same. It is concluded that among various polymers so far studied, P2VP and PS have very similar viscoelastic properties in both bulk and a good solvent (αCN), though the plateau modulus GN0 and steady state compliance Je of P2VP are slightly different from those of PS.
