[en] A solvent-free composition based on epoxyacrylate oligomer dissolved in the monomeric ester of acrylic or methacrylic acid, in a mixture with acrylic acid is curable by radiation and chemical polymerization, by irradiation with accelerated electrons or gamma radiation at a dose of 40 to 150 k.kg^-1. Th polymerization rate depends on reaction conditions, especially o the initiation system, flow rate, composition of the material. I can be affected by the presence of metals of variable valency. The highest acceleration effect was found for the 2,2'-dipyridyl complex of cobalt or manganese octoate or the 2,2'-dipyridyl complex of tin, chromium, cobalt or manganese chloride. Addition in an amount of 0.01 to 3.00 wt.% of metal ion related to the amount of the oligomer, reduces the radiation dose 3 to 4 times. (B.S.)
