The present disclosure is directed to novel derivatives of citronellol and polycitronellol, particularly alkoxylated derivatives of citronellol and polycitronellol, and methods of making them, compositions comprising them, and methods for using them, particularly as surfactants.

The present invention relates to polycondensates containing at least a structural unit, which is an aromatic moiety bearing a polyether side chain, at least a structural unit, which is an aromatic moiety bearing at least one phosphoric acid monoester group, at least a structural unit, which is an aromatic moiety, bearing at least one hydroxy group and at least a methylene unit (—CH.sub.2—), which is attached to two aromatic structural units. The invention also concerns a process for the production of the polycondensates, their use for the dispersion of inorganic binders, for increasing the strength development of concrete and for improving the slump-retention of concrete. The invention relates also to building material mixtures comprising the polycondensates and inorganic binders.

The present invention relates to a polymer comprising repeating units consisting of a substituted pyrrole ring. In particular, the repeating units consist of substituted pyrrole containing polar groups capable of interacting with carbon allotropes such as carbon nanotubes, graphene or nanographites, in order to improve the chemical-physical characteristics of the allotropes mainly by increasing their dispersibility and stability in liquid media and in polymer matrices. The invention also relates to products of addition of these polymers with carbon allotropes in order to obtain easily dispersible macromolecules.

An amphiphilic copolymer includes a first block, a second block and a linker covalently linking the first block with the second block, wherein the first block is a hydrophilic dendritic polyglycerol derivative having a polyglycerol backbone and carrying a plurality of sulfate or sulfonate residues substituting hydroxyl groups of the polyglycerol backbone, wherein the second block is a hydrophobic block comprising a polymer chosen from the group consisting of polycaprolactone, a polylactic acid polymer, and a copolymer of lactic acid and glycolic acid. The linker comprises a hydrocarbon having at least six consecutive methylene residues and a cleavable entity. The linker is devoid of a triazole-containing residue resulting from a reaction between an alkyne and an azide.

Release layers that include an oligomeric component comprising a unit of the Formula (I) are useful for releasably transferring components from one surface to another during manufacturing of microelectronic devices.

The invention relates to vicinal diol ether derivatives of certain polyether polymers, compositions comprising the same, and methods of making the same via reaction with substituted or unsubstituted epoxides, and methods of using the same.
