Natural oils are the attractive biobased alternatives for petroleum derived chemicals in the production of polymers. A series of new biodegradable polymers based on epoxidized camelina oil was synthesized and investigated. The thermal, mechanical, swelling properties, hydrolysis, biodegradation, and bioresistance of the camelina oil-based polymers with bisphosphonate crosslinks were studied and compared with those of the analogous polymers based on epoxidized linseed oil. The dependence of the polymer properties on the density of crosslinks was observed. The obtained results showed that the properties of the camelina oil-based polymers are comparable with those of the linseed oil-based polymers and that camelina oil is a promising starting material for the synthesis of polymers.

Cross-linked polymers are obtained by photopolymerization of glycerol diglycidyl ether 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 changes of rheological properties are examined during the UV curing for the batches of glycerol diglycidyl ether with the different reactive diluents. The dependencies of the mechanical, thermal properties, swelling in the different solvents, biodegradability, and bioresistance of the synthesized polymers on their chemical structure are studied.

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.
