Abstract: A synthesis method for making an isocyanate based organic xerogel having a low density (i.e. 3 ) and a small pore size ( 100m
2 /g is disclosed. The synthesis method avoiding or reducing gel shrinkage during the solvent removal step is characterized by the step wherein the organic solvent used to synthesize the isocyanate based organic xerogel is replaced by water such that during the solvent removal step only water needs to be removed to dry the porous network and to obtain the isocyanate based organic xerogel.
