✦ Synopsis

A study of the cosolvent ternary system, poly(vinyl-2-pyridine)/toluene/ethyl acetate, was carried out by viscometry and light scattering. An anomalous behaviour of the intrinsic viscosity in a certain composition region was observed and attributed to a conformational transition of the chain. The transition is interpreted in terms of the interactions between the constituents of the system.
