摘要： Photopolymers which are derivatives of polyvinyl alcohol and are useful as resists, stencils and relief images are made by reacting a compound having one or two formyl or acetal groups, such as terephthaldehyde, a naphthalene dialdehyde or the reaction product of an acetal and hydroxybenzaldehyde, with an aromatic or heterocyclic compound carrying an acetyl group, so as to produce an intermediate of the formula:
and reacting this with a polyvinyl alcohol to yield a photosensitive product of the formula:
wherein m is 0 or 1, n is an integer from 1 to 6, X is an aromatic or heterocyclic group carrying at least one polar group and Z is an aromatic group of the formula:
wherein R' and R", when both are present, are the same or different and each represents a hydrogen or a halogen atom or an alkyl, alkoxy, hydroxyalkyl, hydroxy, nitro or cyano group.-

摘要： Bei derAcetalisierung von Polyvinylalkohol in einem sau ren wäßrigen Medium in Gegenwart eines Netzmittels bildet sich ein offenporiger fester Schaum, wenn das Reaktionsge misch Gasblasen enthält. Diese Gasblasen werden insbeson dere durch Einrühren von Luft erzeugt. Wird die Acetalisie rung in Gegenwart einer Nucleinsäure durchgeführt, so erhält man einen porösen Formkörper; die Poren liegen in gleich mäßiger Verteilung vor. Der getrocknete Formkörper nimmt ein Vielfaches seines Gewichts an Wasser auf. Er wird als Schwamm in Haushalt und Industrie eingesetzt.
