Abstract: Silicone urethane (meth)acrylates can have at least three (meth)acrylate groups and not more urethane groups than (meth)acrylate groups. A method for preparing the silicone urethane (meth)acrylates involves reacting at least one hydroxy functional silicone (meth)acrylate with at least one isocyanate functional urethane (meth)acrylate. Compositions can contain the silicone urethane (meth)acrylates, and are useful for the production of release coatings, protective films, and protective coatings; and for the manufacturing of 3D printed objects by stereolithography.

Abstract: The invention relates to a silicon dioxide dispersion that comprises a) an outer flowable phase containing 1) polymerizable monomers, oligomers and/or prepolymers that can be converted to polymers by non-radical reaction; and/or 2) polymers, and b) a disperse phase containing amorphous silicon dioxide. The inventive dispersion is characterized in that the average particle size dmax of the silicon dioxide as measured by small angle neutron scattering (SANS) is between 3 and 50 nm at a maximum half-width of the distribution curve of 1.5 dmax. Such a silicon dioxide dispersion can be easily manufactured even at higher concentrations of the disperse phase and can be used to produce polymer materials that have advantageous properties, especially advantageous mechanical properties.

Abstract: The invention relates to a polymeric composition containing: a) at least one epoxy resin; b) at least one copolymer with groups, which react with epoxy resins, and with a glass transition temperature Tg of ?20° C. or lower, c) nanoparticles having a mean particle size dmax ranging from 5 to 150 nm that is measured by means of a small-angle neutron scattering (SANS). The inventive composition enables the production of adhesives, composite materials, coatings and casting compounds exhibiting improved mechanical properties, particularly improve impact strength.
