Cross‐linked polymers were obtained by photopolymerization of epoxidized linseed oil with different reactive diluents (3,4‐epoxycyclohexylmethyl‐3,4‐epoxycyclohexane carboxylate, 1,4‐cyclohexane dimethanol diglycidyl ether, bisphenol A diglycidyl ether, trimethylolpropane triglycidyl ether, and bis[4‐(glycidyloxy)phenyl]methane) using the mixture of triarylsulfonium hexafluoroantimonates as photoinitiator. The kinetic of photocross‐linking reactions of compositions with different concentrations of reactive diluents was investigated. The 69%–91% conversion of epoxy groups of the compositions containing reactive diluents was reached. The mechanical properties, thermal stability, and swelling in polar and nonpolar solvents of the photocross‐linked polymers were studied. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
