摘要：
Stereoregular cellulose-type copoymers, (1 --> 4)-beta-D-ribopyranan derivatives, were prepared by selective ring-opening copolymerization of 1,4-anhydro-2,3-O-benzylidene- and -2,3-di-O-t-butyldimethylsilyl- alpha -D-ribopyranoses with antinomy pentachloride as catalyst at 0-degrees-C. Being subjected to branching reaction, the copolymer can be converted into branched (1 --> 4)- beta-D-ribopyranans.
