Synthesis of polymethacryloyl‐D‐glucose and its copolymers with acrylonitrile. Vinyl polymerization LIV

Abstract 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.
