The elastic behavior of undrawn/annealed swollen thin films of syndiotactic-rich poly(viny1 alcohol), derived from vinyl trifluoroacetate, was studied by repeated elongation/contraction in water. For the films annealed at temperatures below 175"C, the characteristic of deformation was divided into l
The permeabilities of liquids through syndiotactic-rich poly (vinyl alcohol) (s-PVA) very thin films (about 0.3 pm) scooped up from the interface of air/aqueous solution were compared with that of casting s-PVA films (about 15 pm) . The permeability of water decreased with time and the volume of per
The effect of the initial temperature of heating on the elongation of syndiotactic-rich poly(viny1 alcohol) thin films was investigated in water under a load. The elongation ratios Ei after 4 h at fixed temperatures increased roughly with an increase in the initial temperature q and a decrease in th
