초록
이 논문은 napthalimidopropylacrylate(NIPA)와 glycidylmethacrylate(GMA) 공중합체의 합성과 물성에 관한 연구로서 공중합체의 조성, 단량체 반응성비, 공명효과(Q)와 극성효과(e), 나프탈렌발색단을 가진 물질의 형광특성 등을 조사하였다. Azobisisobutyronitronitryl(AIBN) 개시제와 dimethylformamide(DMF) 용매를 60 oC에서 공중합하였다. 단량체의 반응성비는 Fineman-Ross(F-R), Kelen-Tudos(K-T) 법으로 단량체 반응성비를 구한바, r1은 r2보다 크게 나타났다. NIPA이 GMA보다 공중합의 형성이 더 많음을 알 수 있다. 단량체 반응성비의 곱(r1·r2)이 1보다 적어서 불규칙한 교대공중합체가 형성되었고 다른 단량체끼리 결합하게 된 교호공중합체를 형성된 것으로 간주된다. 380 nm에서 약한 분자 형광띠와 460 nm에서 강한 중합체 엑시머 형광띠가 나타났다. NIPA 단량체의 형광수명은 실온에서 UV 355 nm 파장에서 형광붕괴커브를 나타냈으며 5.1449×10-7 s로 나타났다. GMA 공단량체를 아크릴계에 공중합시켜 우수한 내열성 열경화성 접착제나 코팅제에 응용될 것으로 사료된다.
This work, which was about the synthesis of naphthalimidopropyl acrylate and GMA copolymers and their physical properties, investigated the compositions of the copolymer, the reactivity ratios of the monomer, resonance effect (Q), polar effect (e) and fluorescence of naphthalene. Azobisisobutyronitronitryl (AIBN) as an initiator was employed at 60 oC with dimethylformamide (DMF) of solvent for the copolymerization of NIPA. r1 was found to be higher than r2 from the reactivity ratios of the monomer obtained from Fineman-Ross (F-R), Kelen-Tudos (K-T) methods. NIPA was found to be more copolymerized than GMA. r1·r2 product was lower than 1, copolymerization was maked random-alternating type. The fluorescence spectrum of these polymers showed a weak monomer fluorescence band at 380 nm and a strong excimer fluorescence band at about 460 nm. Fluorescence life time of NIPA monomer showed fluorescence cover with UV 355 nm at room temperature, and life time showed 5.1449×10-7 s.
Keywords:3-(1,8-naphthalimido) propyl acrylate;monomer reactivity ratios;resonance effect (Q);polar effect (e);fluorescence life time.
