Abstract A process for the solvent-free production of ethylenically unsaturated polyurethanes (I) comprises preparation of a prepolymer in a discontinuous stirred reactor from an isocyanate containing component (A) and an isocyanate reactive component (B) followed by reaction with a further component (C) in a second continuous reactor to form a polyurethane, whereby at least one of (A), (B), or (C) contains unsaturated groups.
