The OH radical induced oligomerization in dilute aqueous solution of ethyl- and 2-hydroxypropyl acrylate, methyl- and 2-hydroxypropyl methacrylate, acrylamide and methacrylamide, ethyl-fumarate and maleate was investigated by pulse- and steady-state radiolysis. In pulse radiolysis the reactions were observed by measuring the absorbance of the α-carboxyalkyl type radicals. At low concentration (≤1 mmol dm-3) the radicals decay in self-termination. At higher concentration there is a significant deviation from the simple second order behavior due to oligomerization. Computer programs were used to calculate the rate coefficients of propagation and termination at the beginning of oligomerization.
