The invention relates to a process for preparing silica-coated particles of an inorganic expanding agent, the silica-coated particles and their use. The silica-coated particles show a delayed release of the expanding agent particularly in alkaline medium and at elevated temperatures. They are therefore useful in the oil and construction industry.

Silica-coated expanding agents and their use in cementitious systems

What is proposed is the use of hyperbranched polylysine in the development, exploitation and completion of underground mineral oil and natural gas deposits, and in deep wells, especially as a shale inhibitor in water-based drilling muds, completion fluids or stimulation fluids.

Use of polylysine as a shale inhibitor

What is proposed is the use of a water-soluble hydrophobically associating copolymer as an additive in the development, exploitation and completion of underground mineral oil and natural gas deposits and in deep drillings, wherein the copolymer comprises (a) at least one monoethylenically unsaturated monomer (a) selected fromHC&#x2550;C(R)&#x2014;R&#x2014;O&#x2014;(&#x2014;CH&#x2014;CH&#x2014;O&#x2014;)&#x2014;(&#x2014;CH&#x2014;CH(R)&#x2014;O&#x2014;)&#x2014;R&#x2003;&#x2003;(I), and/orHC&#x2550;C(R)&#x2014;O&#x2014;(&#x2014;CH&#x2014;CH&#x2014;O&#x2014;)&#x2014;R&#x2003;&#x2003;(II),and (b) at least one monoethylenically unsaturated, hydrophilic monomer (b) different from monomer (a),wherein the copolymer is obtainable through copolymerization of the monomers (a) and (b) in the presence of at least one surfactant (c).

Use of hydrophobically associated copolymer as an additive in specific oilfield applications

Process for producing actives-comprising polymeric networks from oligomers containing (meth)acrylate groups, optionally from further monomers, and from actives, the polymeric networks obtainable by the process, and the use of the networks for various purposes, more particularly for protecting materials or in crop protection.

Actives-comprising polymer networks, processes for producing them, and their use

The invention relates to radiation-curable compounds, to processes for preparing them, to their use, and to coating compositions comprising them and featuring high scratch resistance.

Radiation-curable compounds

The present invention relates to radiation-curable coating compositions which are of low viscosity and comprise (meth)acrylates and divinyl adipate.
