Abstract
Hydrophilic polyurethane foams containing residues of a polyalkylene glycol monoalkyl or alkaryl ether may be produced by reacting the ether with an isocyanate having a functionality of greater than two and using only stoichiometric amounts or small excesses e.g. up to 12% of weight of water as foaming agent. Methyl, lauryl, cetyl, octylphenyl and nonyl phenyl ethers may be used. The foams are applicable for the manufacture of absorptive devices such as wound dressings, sanitary towels, diapers, incontinence pads or tampons.
