PRESSURE-SENSITIVE ADHESIVE MASS AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a method for producing a pressure-sensitive adhesive mass on the basis of at least one polymer, consisting in subjecting the at least one polymer to cross-linking, said polymer having functional groups Y. In addition, said polymer is mixed with at least one type of functionalized particles having at least one non-polymeric base unit. The invention is characterized in that the particles comprise a surface modification of the base unit, said surface modification of the particles having at least one type of functional groups X and the cross-linking of the polymer being at least partially achieved by a reaction of functional groups X with functional groups Y of the polymer. Also disclosed are pressure-sensitive adhesive masses based on at least one cross-linked polymer component, wherein the polymer component is at least partially cross-linked by the integration of functionalized particles, the particles comprising at least one non-polymeric base unit and a surface modification of said base unit, and wherein the surface modification of the particles has at least one type of functional groups X which are capable of reacting with functional groups Y present in the polymer component. The invention further relates to the use of surface-modified functionalized particles having a non-polymeric base unit as cross-linking reagents for cross-linking polymers for the production of pressure-sensitive adhesive masses.
