ABSTRACT OF THE DISCLOSURE The disclosure describes a relatively homogeneous, three-dimensional,microporous cellular polymer structure com- prising a plurality of substantially spherical cells having an average diameter from about 0.5 to about 100 microns, dis- tributed substantially uniformly throughout the structure, ad- jacent cells being interconnected by pores smaller in diameter than said microcells, the ratio of the average cell diameter to the average pore diameter being from about 2:1 to about 200:1, said pores and said cells being void and said polymer being a synthetic thermoplastic polymer selected from the group consist- ing of olefinic polymers, condensation polymer, oxidation poly- mers and blends thereof. Such solids may be used as master- batches. me microfilms having a sharp pore size distribu- tion and high void volumes may be utilized as filter media.
