Abstract: The material contains interrelated micro- and anisodiametric macropores which latter are disposed mainly on peripheral portions. The volume ratio of micro- and macropores is 1:3-7.The process involves freezing a polymer dispersion at a temperature ensuring a 3-11:1 ratio of dispersed phase to the noncrystallized dispersion medium, seasoning the conjugate-dispersed system at a temperature and within a time sufficient for reversal of phases, followed by thawing. The used polymer dispersion contains a liquid crystallizable dispersion medium and a polymer phase capable of autohesion at temperatures below the initial melting temperature of crystals in the dispersion medium.
