VISCOELASTIC PROPERTIES OF POLY(2-VINYLPYRIDINE) IN BULK AND SOLUTION

Viscoelastic properties of poly(2-vinylpyridine) (P2VP) over a wide ra nge of molecular weight (M) were studied in bulk and solution. It was found that the absolute values of zero-shear viscosity eta(0) of P2VP in bulk and in alpha-chloronaphtharene (alpha CN) are practically the same as those of polystyrene (PS) over whole experimental range of M. The temperature dependence of eta(0) in bulk is also the same. It is c oncluded that among Various polymers so far studied, P2VP and PS have very similar viscoelastic properties in both bulk and a good solvent ( alpha CN), though the plateau modulus G(N)(0) and steady state complia nce J(e) of P2VP are slightly different from those of PS.
