A polyacrylate pressure sensitive adhesive, having an average molecular weight Mw (weight average) of from 100 000 to 600 000 g/mol a polydispersity of not more than 3.0 copolymerized photoinitiator units, and a process for preparing a UV-crosslinkable polyacrylate pressure sensitive adhesive having a polydispersity of not more 3.0, comprising a radical polymerization process for preparing a polymer from a monomer mixture, the monomer mixture to be polymerized comprising copolymerizable photoinitiators, the polymerization process being regulated by the presence of at least one chemical compound comprising the unit -S-C=X, in which X is S, O or N as polymerization regulator.
