Effect of Residual Norbornene-Alkyne Groups on the ROMP Conversion |
| 초록 |
Bottlebrush polymer(BBP) is a type of grafted polymer which has linear backbone attached sidechain. The architecture of bottlebrush polymer provides various and unique properties. Especially, grafting through BBP has high grafting density and causes BBP to display different conformational behavior than linear polymers. Due to these properties, the synthesis of BBP via ROMP has been studied. grafting through BBP, the most widely used method is ROMP after synthesis of macromonomer through CuAAC click reaction. We observed that the ROMP was inhibited by norbornene(NB)-alkyne during this synthesis process. A very small amount of NB-alkyne, which is not removed by precipitation, has had a tremendous impact on ROMP conversion. We found that the conversion was dramatically increased when the NB-alkyne was removed through an additional purification process and have identified changes in ROMP conversion depending on the amount of NB-alkyne through two types of macromonomers, NB-PS and NB-PBA. |
