It is found that the viscosity of a monodisperse polystyrene latex in the disordered state increases anomalously when the disorder-order transition point is approached. This anomalous behaviour is analysed based on the Cohen-Turnbull theory of molecular diffusion in a liquid.

On trouve que la viscosité du latex monodispersé de polystyrène croit anormalement au voisinage du point de transition ordre-désordre lorsqu'on approche dans la phase desordonnee. On analyse le comportement anormal en utilisaut la théorie de Cohen-Turnbull pour la diffusion moléculaire du liquide.
