폴리아릴레이트 - 나일론 6 블록공중합체 : 합성 및 폴리아릴레이트 혹은 나일론 6 단일중합체와의 상용성

Hydroxy-difunctional polyarylate(PAR) 올리고머와 toluene diisocyanate를 반응시켜 합성한 고분자 활성체를 사용하여 ε-caprolactam을 음이온 중합하여 다양한 블록길이의 PAR-nylon 6 블록공중합체들을 합성 하였다. 합성한 블록공중합체들의 열적 성질을 differential scanning calorimeter(d.s.c.)로 측정한 결과, 블록공중합체를 구성하는 PAR 블록과 nylon 6 블록은 부분적 상용성을 가졌으며, 그 정도는 블록의 길이가 짧을수록 컸다. PAR-nylon 6 블록공중합체와 PAR 흑은 nylon 6 homopolymer와의 이원블렌드에서 PAR homopolymer와 PAR 블록, nylon 6 homopolymer와 nylon 6 블록 사이의 분자수준의 섞임을 시사하는 거동을 d.s.c.로 관찰할 수 있었다. Polyarylate(PAR)-nylon 6 block copolymers of various block lengths were prepared by the anionic polymerization of ε-caprolactam using the polymeric activator from hydroxy-difuncrtional PAR and toluene diisocyanate. Phase separated morphology of PAR-nylon 6 block copolymer was suggerted from the thermal properties measured by differential scanning calorometry(d.s.c.). Partial miscbility between PAR block and nylon 6 block of the block copolymers was more evident at shorter length of constituent blocks. In binary blends of PAR-nylon 6 block copolymer with PAR or nylon 6 homopolymer, molecular-level mixing of homopolymers with corresponding blocks of block copolymer was supposed from the thermal properties measured by d.s.c..
Polyacryloyl Chloride 로부터 고분자 염료의 합성
이상원,엄달호,안태완 崇田大學校 1982 論文集 Vol.12 No.1
Several polymeric azo dyes were synthesized from reactive polymer, polyacryloyl chloride. The monomer, acryloyl chloride was synthesized, and then polymerized in N, N-dimethylformamide. Polyacryloyl chloride was reacted with 1, 4-phenylenediamine to poly-N-(4-aminophenyl) acrylamide, and the resulting polymer was investigated by infrared spectroscopy, nuclear magnetic resonance spectroscopy, and elemental analysis. The polymeric azo dyes were obtained by diazotization and coupling reaction of free amine group of the intermediate polymer. The polymeric dyes were insoluble in water and general organic solvents. The colors of these dyes were determined by visible spectrophotometry.
