Abstract

A pressure sensitive adhesive is based on a polymer having a glass transition temperature ≦10° C. and obtained by free-radically initiated polymerization of ethylenically unsaturated monomers in a liquid medium in the presence of >0 and ≦5% by weight, based on the overall amount of the ethylenically unsaturated monomers used for the polymerization, of at least one oligomeric compound itself obtained by free-radically initiated polymerization of ethylenically unsaturated monomers.
