Note that all structures above are not meant to imply regioselective substitution; they are depicted this way only for clarity and simplicity.

AHG anhydroglucose unit.

aPolymers differ only in how they are hydrogenated in the final synthetic step.

bPolymers differ in DS (degree of substitution, Et) of starting material and therefore product from those above.
