Microporous polymeric foams made with silicon or germanium based monomers

(57) Summary silicon and/or polymeric foam material of a germanium base. Copolymerization of the monomer of silicon or a germanium base offers the form which has low glass transition temperature and low density. Moreover, such forms show a comparatively high yield stress value, and they make the form which is especially suitable for absorption of fluid, such as water fluid, such as urine and 経血 (when form is made into hydrophile property). Form has other various uses including application of an insulator.
