Radiation copolymerization of N-vinylpyrrolidone with undecylenic and oleic acids was studied. It was shown that the yield of polymer and the rate of copolymerization are essentially a function of the composition of the starting mixture. The maximum molar concentration of carbonyl units in the copolymer is 30%. A random copolymer in which there is nothing next to the standing carboxylic acid units is formed. The relative reactivity of the acids is equal to zero; the reactivities of N-vinylpyrrolidone - 0.61 < r < 0.94 for undecylenic and 0.90 < r < 1.31 for oleic acids - were calculated in consideration of the effect of the next-to-last unit.
