A method for manufacturing integrated circuit devices, optical devices, micromachines and mechanical precision devices, the said method comprising the steps of (1) providing a substrate having patterned material layers having line-space dimensions of 50 nm and less and aspect ratios of &#x3e;2; (2) providing the surface of the patterned material layers with a positive or a negative electrical charge by contacting the substrate at least once with an aqueous, fluorine-free solution S containing at least one fluorine-free cationic surfactant A having at least one cationic or potentially cationic group, at least one fluorine-free anionic surfactant A having at least one anionic or potentially anionic group, or at least one fluorine-free amphoteric surfactant A; and (3) removing the aqueous, fluorine-free solution S from the contact with the substrate.

A process for preparing hyperbranched polyols by reacting epoxy alcohols in the presence of phosphines.

Method for the phosphine-initialized production of hyperbranched polyols

The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction being carried out in the presence of a polycondensate containing at least one structural unit consisting of an aromatic or heteroaromatic moiety bearing a polyether side chain and at least one structural unit consisting of an aromatic or heteroaromatic moiety bearing at least one phosphoric acid ester group and/or its salt. The invention concerns a composition of calcium silicate hydrate and the polycondensate, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.

The present invention relates to a process for producing polymer-containing coatings for surfaces by in situ precipitation of calcium carbonate. The invention is additionally directed to the polymer-containing coating as such and to surfaces to which such polymer-containing coatings have been applied. The polymer-containing coatings preferably have antibacterial action.

The invention concerns a process for the preparation of a hardening accelerator composition by reaction of a water-soluble calcium compound with a water-soluble silicate compound and a process for the preparation of a hardening accelerator composition by reaction of a calcium compound with a silicon dioxide containing component under alkaline conditions, in both cases the reaction of the water-soluble calcium compound with the water-soluble silicate compound being carried out in the presence of an aqueous solution which contains a water-soluble comb polymer suitable as a plasticizer for hydraulic binders. The invention concerns also a composition of calcium silicate hydrate and comb polymer, its use as hardening accelerator and for the reduction of the permeability of hardened compositions.
