This part of ISO 15023 specifies the methods to be used in determining the properties of poly(vinylalcohol), which is normally prepared by hydrolysis of poly(vinyl acetate) and whose compositioncomprises vinyl alcohol monomeric units and vinyl acetate monomeric units. This part of ISO 15023 isapplicable to poly(vinyl alcohol) with a vinyl alcohol unit content (degree of hydrolysis) from 70 mol%to 100 mol%.In addition to the designatory properties specified in ISO 15023-1 (degree of hydrolysis and viscosity ofan aqueous solution), this part of ISO 15023 includes a number of other properties which are commonlyused to specify PVAL materials (see Table 1).
