Different historic textiles were subject to aqueous treatments with and without sodium borohydride as a reducing agent. As the action of borohydride generates an alkaline environment that is potentially harmful for oxidized cellulose in historic textiles, two less alkaline treatment options using buffer systems were additionally tested.In order to track the impact of the treatments on the samples,...
Three methyl celluloses with completely uniform substitution pattern, 2-O-methyl cellulose (1), 3-O-methyl cellulose (2) and 6-O-methyl cellulose (3), were prepared according to the cationic ring opening polymerization approaches starting from substituted 1,2,4-orthopivalate derivatives of d-glucose. These samples allowed for the first time to sort out the methyl substitution effects on solid-state...
