The present invention relates to a process for purifying monomers, by evaporating at least a portion of the monomers present in a starting composition and then condensing it, which is characterized in that at least a portion of the starting composition is evaporated in a short-path evaporator, the mass flow density of the vapours dot over (m)} being selected according to the relation (I)

tilde over (M)} is the average molar mass of the vapours in the short-path evaporator in kg/kmol
T is the temperature of the vapours in K
