Abstract
The present invention provides a gel comprising a physical network formed of polymer chain crystallites interconnected by amorphous chain segments. Functionalization of the chain segments between the crystallites forms a blocky distribution of functionality along the chain whereby the functionalities are concentrated in groups consisting of one or more functionalities, separated by non-functionalized runs of crystallizable segments of the polymer. Removal of the solvent from the gels, without reducing the gel volume, forms an aerogel.
