Abstract
Abstract
During gelation and fusion process PVC plastisols changes from a suspension of resin particles in a liquid plasticizer to a uniform mass. The manner of change was observed with a scanning electron microscope, SEM. Four different plasticizers varying solvent power were used: they were dioctyl phthalate, dioctyl sebacate, dibutyl sebacate and tricresyl phosphate. Significant differences were observed among different plasticizer systems in a manner of dissolution of PVC into a plasticizer, swelling of PVC particles with a plasticizer and fusing to form a uniform mass. The SEM micrographs are presented with reference to the viscoelastic properties at the corresponding temperature.
