    Description / Table of Contents: Poly-3-O-methacryloyl-D-glucose (PMG) wurde durch Hydrolyse des durch radikalische Polymerisation von 3-O-Methacryloyl-1.2,5.6-diisopropyliden-D-glucose (MDG) gewonnenen Polymerisates (PMDG) hergestellt. MDG wurde durch Reaktion von 1.2,5.6-Diisopropyliden-D-glucose mit Methacrylsäurechlorid synthetisiert. PMG war in Wasser oder Dimethylsulfoxyd löslich, jedoch in anderen organischen Lösungsmitteln unlöslich. Es reduzierte FEHLINGsche Lösung und war optisch aktiv. PMG schmeckte leicht süßlich.MDG wurde mit Acrylnitril copolymerisiert. Das so gewonnene Copolymerisat wurde mit einer sauren Lösung von Zinkchlorid hydrolysiert. Das hydrolysierte Copolymerisat besaß reduzierende Eigenschaften und war in Dimethylformamid und in wäßriger ZnCl2-Lösung löslich. Durch Erhitzen mit einem wasserlöslichen Farbstoff ließ es sich anfärben.
    Notes: 3-O-methacryloyl-1,2,5,6-diisopropylidene-D-glucose (MDG) was synthesized from 1,2,5,6-diisopropylidene-D-glucose and methacryloyl chloride. It was polymerized to PMDG using azo-bis-isobutyronitrile as initiator. Poly-3-O-methacryloyl-D-glucose (PMG) was prepared by hydrolysis of PMDG. PMG was soluble in water or dimethyl sulfoxide but insoluble in other organic solvents. It reduced FEHLING's solution and showed an optical activity. PMG tasted a little sweet.MDG was copolymerized with acrylonitrile. The copolymer was hydrolyzed in acidic solution of ZnCl2. The hydrolyzed copolymer showed a reducing power, and was soluble in DMF or aqueous ZnCl2 solution. It was well dyed by water soluble dyes.
