Abstract
Method for producing contact adhesive masses containing acrylic, by coupling at least one component to at least one other reactive constituent contained in at least one other component, the at least one reactive constituent having at least two functional groups and the at least one constituent in the at least one other component containing at least two functional groups.
Claims40
A process for producing a pressure-sensitive adhesive which is constructed by coupling at least one reactive constituent present in at least one component with at least one further reactive constituent present in at least one further component,
- the at least one reactive constituent in the at least one component containing at least two functional groups, and the at least one constituent in the at least one further component containing at least two functional groups;
- at least one reactive constituent of at least one component employed being a functionalized acrylate copolymer which has a weight average of its molar mass distribution between 5000 g/mol and 200 000 g/mol, the acrylate copolymer being a copolymer constructed from at least one nonfunctionalized kind of monomer and at least one functionalized kind of monomer, the at least two functional groups being introduced in the form of the copolymerized functionalized kind of monomer;
- and
- the components for preparing the pressure-sensitive adhesive being processed solventlessly.
