Abstract
The invention relates to a prepolymer material based on monomeric, oligomeric or polymeric compounds with at least one ethylenically unsaturated (meth)acryloyl group. The problem of imperfect imprinting properties, escpecially of an unwanted adhering to the imprinting stamp or mold, is circumvented by a fluorinated organo silane surfactant as an additional component of the prepolymer material. Furthermore, the invention describes an imprinting process for the manufacture of polymer articles with relief on their surface. Better release properties of the polymer article from the stamp or mold are accomplished by applying a surfactant, comprising a fluorinated organo silane, onto the surface of the mold or stamp.
