ABSTRACT:
Rapid set cellular articles can be prepared from a latex by the steps of: a) frothing a latex that contains a dispersed polymer having pendant cationic groups or adsorbing cationic molecules or both, and pendant acid groups; and b) rendering the frothed latex sufficiently basic to make the cellular article. The cellular articles of the present invention are advantageously prepared at ambient temperatures and pressures, and in the absence of organic solvents or CFCs.
