Plastics - Poly(vinyl alcohol) (PVAL) materials - Part 2: Determination of properties (ISO 15023-2:2019)
This document specifies the methods to be used in determining the properties of poly(vinyl alcohol), which is normally prepared by hydrolysis of poly(vinyl acetate) and whose composition comprises vinyl alcohol monomeric units and vinyl acetate monomeric units. This document is applicable 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 of an aqueous solution), this document includes a number of other properties which are commonly used to specify PVAL materials (see Table 1).
Kunststoffe - Polyvinylalkohol (PVAL)-Werkstoffe - Teil 2: Bestimmung von Eigenschaften (ISO 15023-2:2019)
Dieses Dokument legt die Verfahren fest, die bei der Bestimmung der Eigenschaften von Polyvinylalkohol anzuwenden sind, der gewöhnlich durch Hydrolyse von Poly(vinylacetat) hergestellt wird und dessen Zusammensetzung monomere Einheiten von Vinylalkohol und von Vinylacetat einschließt. Dieses Dokument gilt für Polyvinylalkohol mit einem Gehalt an Vinylalkoholeinheiten (Hydrolysegrad) von 70 % (Stoffmengenkonzentration) bis 100 % (Stoffmengenkonzentration).
Zusätzlich zu den in ISO 15023 1 festgelegten kennzeichnenden Eigenschaften (Hydrolysegrad und Viskosität einer wässrigen Lösung) enthält dieses Dokument eine Reihe von weiteren Eigenschaf¬ten, die gewöhnlich für die Spezifikation von PVAL Werkstoffen verwendet werden (siehe Tabelle 1).
Plastiques - Matériaux en poly(alcool de vinyle) (PVAL) - Partie 2: Détermination des propriétés (ISO 15023-2:2019)
Le présent document spécifie les méthodes à utiliser pour déterminer les propriétés du poly(alcool de vinyle), normalement préparé par hydrolyse du poly(acétate de vinyle) et qui comprend, dans sa composition, des monomères d'alcool de vinyle et des monomères d'acétate de vinyle. Le présent document s'applique aux poly(alcool de vinyle) ayant une teneur en monomères d'alcool de vinyle (degré d'hydrolyse) allant de 70 mol % à 100 mol %.
Outre les propriétés de désignation spécifiées dans l'ISO 15023‑1 (degré d'hydrolyse et viscosité d'une solution aqueuse), le présent document inclut un certain nombre d'autres propriétés communément utilisées pour spécifier les matériaux en PVAL (voir Tableau 1).
Polimerni materiali - Materiali na osnovi polivinilalkohola (PVAL) - 2. del: Ugotavljanje lastnosti (ISO 15023-2:2019)
Ta dokument določa metode za ugotavljanje lastnosti polivinilalkohola, ki se običajno pripravlja s hidrolizo polivinilacetata in katerega sestava zajema monomerne enote vinilalkohola ter monomerne enote vinilacetata. Ta dokument se uporablja za polivnilalkohol z vsebnostjo enote vinilalkohola (stopnjo hidrolize) od 70 do 100 mol%.
Poleg označevalnih lastnosti, določenih v standardu ISO 15023-1 (stopnja hidrolize in viskoznosti vodne raztopine), ta dokument vključuje številne druge lastnosti, ki se pogosto uporabljajo za opredelitev materialov PVAL (glej preglednico 1).
