Effect of Norbornenyl Comonomer Design on Dynamic Covalent Polymerization with Chalcogenide Hybrid Inorganic/Organic Polymer Resins |
| 초록 |
Herein, we report on the preparation of chalcogenide hybrid inorganic/organic polymers (CHIPs) derived from elemental sulfur which was obtained by using bifunctional norbornene comonomers (NC) from dynamic covalent polymerization (DCP). For this study, p(S-r-Sty) resin was prepared by inverse vulcanization. A series of new NCs which contain thioether, disulfide, benzylic ether units were designed for demonstrating the effect of molecular architectures. Sulfur radicals generated by fragmentation of p(S-r-Sty) were then able to undergo thiol-ene addition to norbornenyl comonomers resulting in the formation of new CHIP terpolymers as characterized by 1H NMR, FT-IR, SEC, elemental analysis, and DSC. From the change of molecular weight and Tg after DCP, we demonstrate the effect of comonomer design on copolymerizations with sulfur resins. These results point to the need for enhanced screening methods to optimize structure-reactivity design parameters for future studies. |
