## Abstract The light transmittance of the gels of poly(vinyl alcohol) (PVA)/phenol/water solutions was examined for the entire range of phenol/water content. Excellent transparency was found for the gels with phenol contents of 70–95 vol %. In full consideration of the results for the transparency

The structure and properties of syndiotacticity-rich poly(vinyl alcohol) (s-PVA) prepared through the saponification of drawn poly(vinyl trifluoroacetate) (PVT-FAc) with gaseous ammonia were studied. The PVTFAc samples with s-diad % of 59 and 64 were used. The s-PVAs had low densities and showed X-r
