Abstract:
1. A solvent-free pressure-sensitive adhesive comprising at least one crosslinked polymer component having a molar mass of between 100,000 to 500,000, the crosslinking of the polymer component being brought about at least in part by incorporation of functionalized particles, the particles having at least one clay mineral base unit with a surface modification of this base unit, and the surface modification of the particles, wherein the surface modification is brought about by means of surface modification reagents selected from the group consisting of organosilanes, surfactants, organotitanium compounds, fatty acids and polyelectrolytes, the surface modification of the particles further having at least one kind of functional groups which are capable of reacting with functional groups present in the polymer component.
