Radical Cyclopolymerization of Isocyanurate Core-Based Bifunctional Monomers Bearing a Hydroxy Group and Their Application to Cross-Linking Reaction

We report the synthesis of linear polymers having macrocyclic units in the main chain and hydroxy groups in the side chains by radical cyclopolymerization of the isocyanurate core-based bifunctional monomers and their utilization to cross-linking reaction via esterification. The 5% weight loss temperature (Td5) and glass transition temperature (Tg) of the resulting linear polymers have clearly revealed the effect of the introduced macrocyclic unit upon the thermal stability of the polymer. Among the synthesized cross-linked polymers, the rigidity of the incorporated cross-linked structure in the cross-linked polymers also dominates thermal properties of polymers. Such reactive linear polymers including macrocyclic units and hydroxy groups are expected to be applied to various fields of high thermal-resistance materials.
