Abstract
The present invention relates to a composition comprising at least one amphiphilic glycidyl ether copolymer composed of special structural units I to V, wherein at least one of the structural units I has an aromatic group, and wherein the structural units may each be arranged in a block, a gradient or randomly, as a dispersant and a dispersed solid matter or as an emulsifier and an unsaturated polymer system in the form of a water-in-oil emulsion to be cured.
Claims23
A composition comprising at least one amphiphilic glycidyl ether copolymer 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—R4 and/or R5, in which
- R1 is a linear or branched alkyl radical having preferably 1-20 C atoms or a cyclic alkyl radical having preferably 4-10 C atoms, an aryl radical, an arylalkylene radical, a heteroaryl radical or heteroaryl alkylene radical, in each of which the aryl or heteroaryl ring may be substituted;
- R2, 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 R2 are an OH-protective group, preferably acetal group or tert-butyl group;
- R3 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;
- R4 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 which has preferably at least 2, more preferably 2-5 repeating units with an alkoxy group having preferably 1-5 C atoms;
- R5, identical to or different from R2, is a residue with the definition of R2 with the exception of OH-protective groups,
- the structural units being of gradientlike, random or respectively blocklike arrangement, and
- the structural unit I being present at least 2 times, preferably 2 to 100, more preferably 2 to 50 times, of which at least one of the 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.
