Hochmolekulare Verbindungen, 9. Mitteilung: Über Poly‐vinylacetat und Poly‐vinylalkohol

Abstract: Um in die besondere Natur der hochmolekularen Naturstoffe einzudringen, schien es zweckmaBig, Modelle einfacher, synthetischer Verbindungen zu studieren2). So gewahren z. B. die P o l y -o x y m e t h y l e n e einen Einblick in den Bau der Cellulose3). Urn AufschluB uber die kolloiden Losungen der S t a r k e zu erhalten, wurde eine einfache, kolloid-losliche, hydroxylhaltige Verbindung hergestellt in der Hoffnung, daS eine solche Vergleiche init der Starke zuliefle. Ein solcher Stoff ist der P o l y -v i n y… Show more

“…Pizzirani et al prepared this polymer by bulk p~lymerization.~ But this method is troublesome in the synthesis of monomer, and the conversion should be kept low in order to prevent crosslinking. Another method for the preparation of this polymer was reported by Staudinger et al 5 and Noma et a1. 6 We adopted this procedure as follows, In a glass apparatus protected from moisture by a calcium chloride tube, 5 g of poly(viny1 alcohol) was suspended in 100 mL of anhydrous pyridine and heated overnight with stirring at 90°C.…”

“…PVAiodine complex (I 2 PVA), which was discovered in 1927 independently by Staudinger et al [135] and Her rmann and Haehnel [136], is of practical importance as an antiseptic in medicine. Very interesting research, still going on, is the study of the effect of tacticity, molecu lar weight and branching of PVA ( Figure 7B), and of the content of residual acetyl groups on the I 2 PVA complex formation [137][138][139][140][141][142].…”

“…It is well known that PVA forms iodine complexes by changing color from brown to blue. 10,11 Iodine/PVA complexation occurs both in an aqueous solution and in a swollen gel state of PVA. For example, in solution, the amount of complex in-creases with increasing concentrations of PVA, iodine, and boric acid.…”
