2,2-dinitropropyl acrylate (DNPA), 2,2-dinitrobutyl acrylate (DNBA) and 2,2-dinitrobutyl methacrylate (DNBMA) were synthesized
and the kinetics of their free-radical polymerization in the presence of 2,2′-azobisisobutyronitrile (AIBN) were investigated
by DSC in the non-isothermal mode. The kinetics of the free-radical polymerization as estimated by the Kissinger and Ozawa
methods showed that the reaction is disfavoured by increasing steric hindrance around the acrylyl double bond. The rate constants
calculated from the activation parameters showed the structural dependency. The polymerization kinetics revealed that the
polymerizability of three monomers decreased due to the presence of substituent methyl groups on the acrylyl double bond and
2,2-dinitrobutyl on ester group. Thus, the polymerization tendency increased in the order DNPA>DNBA>DNBMA.
