Both the viscosity of a plastisol comprising a dispersed polymer, a plasticizer for the polymers and at least one liquid diluent, and exudation of liquids from articles formed from the plastisol are minimized when the difference between 1) the weighted average of the Hildebrand solubility parameter values of all liquid ingredients, including plasticizer, in the plastisol and 2) the Hildebrand solubility parameter of the dispersed polymer is + 0.6 to +1. The plastisols of the present invention are suitable for fabrication into films and molded objects, and as coating materials for a variety of metallic and non-metallic substrates.
La viscosité d'un plastisol, et l'exsudation de liquides d'articles formés à partir du plastisol comprenant un polymère dispersé, un plastifiant du polymère et au moins un diluant liquide peuvent être réduites lorsque la différence entre 1) la moyenne pondérée des paramètres de solubilité d'Hildebrand de tous les ingrédients liquides du plastisol dont le plastifiant et 2) le paramètre de solubilité d'Hildebrand du polymère dispersé, est de + 0,6 à +1. Les plastisols de l'invention peuvent servir à la fabrication de films et d'objets moulés, ou comme matériau de revêtement de différents substrats métalliques et non métalliques.
