Notes:
Methyl mono- and methyl di-O-allyl-α-D-glucosides are prepared by the reaction of methyl α-D-glucoside with allyl chloride in alkali in a two-phase system. The monoallyl ether consists mainly of a mixture of methyl 2-, 4-, and 6-O-allyl-α-D-glucosides, the diallyl compound of 2,6- and 4,6-di-O-allyl-α-D-glucosides in approximately a 1 : 1 ratio. Both compounds are homopolymerized with oxygen as the catalyst. The poly(monoallyl glucoside) is a water-soluble, brittle, clear resin with a softening point of 100-110°C. The poly(diallyl glucoside) is a brittle, clear, but completely insoluble resin with no softening point. Copolymerization with acrylamide under certain conditions yields water-soluble polymers, aqueous solutions of which exhibit high viscosities and have the typical appearance and consistencies of those of polysaccharides.
