The invention relates to metal oxide or semimetal oxide nanoparticles having an average particle size of from 2 to 250 nm, characterized in that the nanoparticles have at least two different, free-radically polymerizable groups on the surface. The invention further relates to nanocomposites produced from such nanoparticles and also processes for producing them.

Inorganic nanoparticles and polymer composite produced therefrom

The invention relates to a method for producing hybrid-particles containing polymer and SiO-particles, wherein

Method for producing hybrid particles

The invention relates to a composition containing at least one plasticizer and silicon dioxide particles having an average particle size of 150 nm or less. According to the invention, the proportion of silicon dioxide particles is from 10 to 80% by weight and the proportion of plasticizer is from 90 to 20% by weight, where the sum of the proportions of silicon dioxide particles and of the plasticizer is at least 80% by weight. The invention makes it possible to mix nanoparticles into any polymeric materials in a simple way.

Plasticizer composition

The invention provides a polymerizable composition which comprises:

Polymerisable mass with cross-linking nanoparticles

The invention relates to a polymerizable composition containing:

The subject matter of the invention is a method for the removal of alkaline or acidic compounds from a solvent-containing metal oxide dispersion, having the following steps: a. conversion of the solvent into gas phase; b. condensation of the solvent; c. bringing the condensed solvent into contact with a neutralizing agent; d. Return of the condensed solvent into the metal oxide dispersion.
