Abstract:
1. A plastisol comprising: A. a dispersed phase comprising particles of polyvinyl chloride polymer; and B. a liquid phase comprising 1) a plasticizer for said polymer, the plasticizer selected from the group consisting of diesters of benzoic acid and dihydric alcohols, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol and 1,3-butanediol, and 2) from 5 to 55 weight percent, based on the total weight of said liquid phase, of an organic diluent; wherein a weighted average of individual Hildebrand solubility parameter values for ingredients of the liquid phase of said plastisol differs from Hildebrand solubility parameter value of said polymer by about ±0.6 to about ±1.0, and wherein the plastisol has a lower viscosity than a plastisol where a weighted average of individual Hildebrand solubility parameter values for ingredients of the liquid phase differs from Hildebrand solubility parameter value of the polymer by an amount outside of a range of about ±0.6 to about ±1.0.
