For this purpose, four divinyl monomers whose double bonds had different polymerization reactivity were designed, and then properties were calculated based on density functional theory (DFT) using standard B3LYP/6 - 31g(d), B3LYP/6 - 31 + g(d,p), and B3Iyp/6-311 + g(3df,2pd) method and basis set combinations.
