Patent ID: 8367762

Claim:
A composition comprising at least one amphiphilic glycidyl ether copolymer of blocklike construction, constructed from the following structural unit I and at least one of the following structural units II-V, the structural unit IV always being arranged together with at least one of the structural units II, III, and V, and from the end groups —O—R 4 and/or R 5 , in which R 1 is a linear or branched alkyl radical or a cyclic alkyl radical, an aryl radical, an aryl alkylene radical, a heteroaryl radical or heteroaryl alkylene radical, in each of which the aryl or heteroaryl ring may be substituted; R 2 , identical or different at each occurrence, is hydrogen and/or is a carboxymethylene group or a corresponding salt or a corresponding alkyl ester group, a monoester radical of maleic acid or a corresponding mono salt, a phosphoric acid radical or a corresponding salt, a sulfonic acid radical or a corresponding salt or a sulfosuccinic acid radical or a corresponding salt, or up to 20% at most of the radicals R 2 are an OH-protective group; R 3 is hydrogen and/or a linear or branched alkyl radical having 1 to 6 C atoms and/or a cyclic alkyl radical having 4-6 C atoms; R 4 is a linear, branched or cyclic alkyl radical which may be substituted by at least one aryl radical or arylalkylene radical, or is an optionally substituted aryl radical or arylalkylene radical or a polyalkylene oxide radical; R 5 , identical to or different from R 2 , is a residue with the definition of R 2 with the exception of OH-protective groups, the structural units being of gadientlike, random or respectively blocklike arrangement, and the structural unit I being present at least 2 times, the glycidyl ether copolymer has at least one block of the repeating structural unit I, of which at least one of the repeating structural units I carries an aromatic radical, and where the fraction of the optionally present structural units IV is 0% to 50% at most of the total number of structural units II to V, as dispersant and at least one dispersed solid or as emulsifier and an unsaturated polymer system, which is to be cured, in the form of a water-in-oil emulsion, with the provisos that (i) an aqueous composition of a glycidyl block copolymer comprising 5 phenyl glycidyl ether units and 67 ethylene oxide units and an active pharmaceutical ingredient is excluded and (ii) an aqueous composition of a glycidyl block copolymer consisting of 2 blocks each comprising 71 or 62 or 38 ethylene oxide units and an intermediate block of 7.8 or 12 phenyl glycidyl ether units and an active pharmaceutical ingredient is excluded.
