    • Processes for producing a hydroxyalkyl(meth)acrylate which comprise reacting (meth)acrylic acid with an alkylene oxide in the presence of a catalyst. A first process is characterized in that the amount of the acid ingredient is kept, on calculation, at 0.010 or more in terms of molar ratio to the catalyst present in the liquid reaction mixture and that the liquid reaction mixture from which the hydroxyalkyl(meth)acrylate has been distilled off is used in the subsequent reaction. A second process is characterized in that a dialkylene glycol mono(meth)acylate is supplied to the reaction system to cause the dialkyleneglycol mono(meth)acylate to coexist in the liquid reaction mixture.
