새로운 스피로 오르토 카보네이트의 합성 및 중합반응
A new spiro-ortho carbonate containing bulky side group, 3,9-di-(9,10-dihydro-9,10-ethanoanthracenyl)-1,5,7,11-tetraoxaspiro-5,5-undecane 4 was prepared and polymerized with BF3${\cdot}$etherate as initiator. Densities of monomer and polymer were measured using dilatometer and it was demonstrated th...

Zusammenfassung: | A new spiro-ortho carbonate containing bulky side group, 3,9-di-(9,10-dihydro-9,10-ethanoanthracenyl)-1,5,7,11-tetraoxaspiro-5,5-undecane 4 was prepared and polymerized with BF3${\cdot}$etherate as initiator. Densities of monomer and polymer were measured using dilatometer and it was demonstrated that the bicyclic monomer 4 underwent expansion on polymerization. Bulky 한 side group을 갖는 새로운 스피로 오르토 카보네이트, 3,9-di-(9,10-dihydro-9,10-ethanoanthracenyl)-1,5,7,11-tetraoxaspiro-5,5-undecane 4을 합성하고 $BF_3{\cdot}etherate$를 개시제로 개환 중합시켜 poly(ethercarbonate) 5를 합성하였다. 단량체와 중합체의 밀도를 측정하여 단량체 4는 다른 단량체와는 달리 중합시 부피증가를 수반하는 것을 확인하였다. |
