PROPERTIES OF FURANIC MONOMERS

The relevant properties of furanic compounds covered in this review are summarized in Table 1.

The compositions of poly2 and poly3 were studied by several groups [2,3] and shown to have mainly the following structures:

Their relative abundance depends, of course, on the conditions used for their syntheses. A typical composition [3] is given in Table 2.
