Surface tensions (γs) and their surface tension components (γsd, γsP) of polyvinylformal (VinylonR, formalization degree 9.463.1 mol%), cellulose acetate (acetylation degree 38.443.8%), cellophane, and iron (III) oxinate were calculated from extended Fowkes' equation and Wu's equation. (Table-2, 3, 4) <BR>The polar force component values (γsP) from Wu's equation were a little bigger than those from extended Fowkes' equation. <BR>The polar force components (γsP) of Vinylon showed the minimum value when the formalization degree was about 35%. This indicated that the surface tension of Vinylon was minimum at the same formalization degree. <BR>It was also revealed that the polar force components (γsP) of cellulose acetate and cellophane decreased with increasing the acetylation degree whereas the surface tension (γs) decreased with increasing the acetylation degree. <BR>The surface tension values listed in Table-2, 3, 4 may be helpful for calculating the work of adhesion (Wa) in detergency and adhesion studies.
