The present invention relates to a process for producing high-purity hydrosilylation products, and also to the products that may be produced by this process and to the use thereof as surfactants.

Process for producing high-purity hydrosilylation products

The present invention relates to a formulation comprising a polyether siloxane, which is characterized in that a polyether that is terminated with an ester group and that is different from the polyether siloxane is present in the formulation in an amount of from 0.5 to 10% by weight based on the complete formulation, to a process for the production of a defoamed composition, wherein the inventive formulation is added to the composition to be defoamed, and to a composition comprising a formulation according to the invention, wherein the composition is a coating agent, a paint or a varnish.

Formulation and its use as defoamer

The present invention relates to a process for producing hydrosilylatable, eugenol-based polyethers, to the conversion thereof into polyether siloxanes and also to the products that may be produced by this process and to the use of said products as surfactants.

Acrylate-terminated urethane polybutadienes from low-monomer 1:1 monoadducts from reactive olefinic compounds and diisocyanates and hydroxy-terminated polybutadienes for liquid optically clear adhesives (LOCAs)

The invention provides polyglycerol alkoxylate esters and for the preparation and use thereof.

Polyglycerol alkoxylate esters and preparation and use thereof

Described are a process for producing hydrosilylable polyoxyalkylene ethers, comprising the steps of (1) alkoxylation of at least one terminally unsaturated alcohol with alkylene oxides to afford a polyoxyalkylene ether, (2) etherification of the polyoxyalkylene ether from step (1) and (3) neutralization of the product from step (2) under buffered conditions, and hydrosilylable polyoxyalkylene ether mixtures.

Process for producing hydrosilylable polyoxyalkylene ethers

Process for the preparation of eugenol polyethers that can be hydrosilylated and eugenol polyethersiloxanes and use thereof

Alkoxysilyl-containing adhesive sealants having improved tear propagation resistance

The present invention relates to compositions comprising eugenol polyethers and/or eugenol polyethers modified with siloxanes, and to the use of eugenol polyethers in polyether siloxanes based on these eugenol polyethers as wetting agents.

Use of eugenol polyethers and eugenol polyether siloxanes as wetting agents

The present invention provides specific alkoxylation products, a process for preparing them, compositions comprising these alkoxylation products, and their use.

Alkoxysilyl-containing adhesive sealants with intrinsically reduced viscosity

This invention relates to a method for producing a water-absorbing polymer, including the following steps: (i) mixing (&#x3b1;1) 0.1 to 99.999 wt % polymerizable, ethylenically unsaturated, acid-group-containing monomers; (&#x3b1;2) 0 to 70 wt % polymerized ethylenically unsaturated, monomers copolymerizable with (&#x3b1;1); (&#x3b1;3) 0.00 1 to 10 wt %, cross-linking agent(s); (&#x3b1;4) 0 to 30 wt % water-soluble polymers; and (&#x3b1;5) 0 to 20 wt % additive(s), wherein the total quantity by weight of (&#x3b1;1) to (&#x3b1;5) amounts to 100 wt %, (ii) radical polymerization while cross-linking, in order to form a hydrogel polymer, (iii) drying the hydrogel polymer, (iv) grinding and sifting the water-absorbing polymer, (v) surface post-cross-linking the hydrogel polymer, and (vi) drying and processing the polymer, wherein, before the admixture of the initiator and the start of radical polymerization, 0.01 to 5 wt % of a surfactant, relative to acrylic acid, 0.01 to 5 wt % foaming agent, are added.
