Abstract
The present invention related to particles and composite particles, their uses and a novel process for producing them from alkoxysilyl-group-carrying alkoxylation products.
Claims10
Process for producing particles or composite particles by condensation of alkoxysilyl-group-carrying alkoxylation products with a molar mass greater than or equal to 300 g/mol,
- characterized in that the alkoxysilyl-group-carrying alkoxylation products have at least one hydroxyl group;
- and
- characterized in that the particles or composite particles are produced by condensation of an emulsified organic phase comprising at least one alkoxysilyl-group-carrying alkoxylation product, in an aqueous, optionally solids-stabilized phase and optionally in the presence of a catalyst.
