Furfuryl alcohol polymerizes in a suspension of dispersed inorganic so
lids such as silica in 1,2-dichloroethane using trifluoroacetic acid a
s initiator. Depending on the experimental conditions the reactions le
ad to 1) agglomeration of particles, 2) composite and soluble polymer
formation, 3) composite formation. The chemical structure of the solub
le polymers is not regular but the furfurylic sequence is predominant.
The polymer grafted on the surface of the solid is a strongly reticul
ated poly(furfuryl alcohol), which also possesses conjugated double bo
nds that are involved in an acid-base equilibrium with trifluoroacetic
acid.
