The nucleophilic addition reaction of dipropylamine to vinyl groups of multiacrylate - poly(2-acryloyloxyethyl methacrylate) and to 2-butyrylethyl acrylate as model compound has been investigated. Based on the results obtained, it has been shown that the addition reaction rate of dipropylamine to multiacrylate and 2-butyrylethyl acrylate is proportional to [CH2=CH-] and to [(C3H7)(2)NLi] with the ratio [(C3H7)(2)NH] (o) / [(C3H7)(2)NLi] (o) = 20. Second-order addition reaction rate constants and activation energies for the systems under investigation have been determined.
