ABSTRACT:
Novel extended polymer surfactants comprising a methoxy-terminated polyethylene glycol hydrophilic block acylated with a hydrophobic moiety comprising a chain of at least two fatty acid units, e.g. an acyloxyacyl group such as 16-hexadecanoyloxyhexadecanoyl, are useful in the preparation of polymer-based gas-containing contrast agents by emulsion techniques.
