摘要
Fluoro-terminated hyperbranched（poly（aryl） ether ketone）（HPOP-PEEK-F） with 4-phenoxyphenyl side groups was prepared from A2（2-（4-phenoxyphenyl）-1,4-diphenol） and B3（1,3,5-tris[4-（4-flourobenzoyl） phenoxy]benzene） with a function group ratio of 0.48:1（A2:B3）.The chemical structure of HPOP-PEEK-F was confirmed by FTIR and（）1H-NMR.The degree of branching（DB） of HPOP-PEEK-F was 0.66 determined by（）1H-NMR measurements.The phenyl ethynyl-terminated hyperbranched poly（ether ether ketone）（HPOP-PEEK-PEP） was prepared by the end-capping approach.The HPOP-PEEK-PEP showed high glass transition temperature than HPOP-PEEK-F,but exhibited lower thermal stability.After cross-linking,the glass transition temperature,thermal stability and anti-chemical corrodibility of HPOP-PEEK-PEP were all improved.
Fluoro-terminated hyperbranched poly（aryl ether ketone） （HPOP-PEEK-F） with 4-phenoxyphenyl side groups was prepared from A： （2-（4-phenoxyphenyl）-l, 4-diphenol） and B3 （ 1,3, 5-tris [4-（4-flourobenzoyl） phenoxy]benzene） with a function group ratio of 0.48：1 （A2 ： B3 ）. The chemical structure of HPOP-PEEK-F was confirmed by FTIR and ^1H-NMR. The degree of branching（DB） of HPOP-PEEK-F was 0.66 determined by ^1 H- NMR measurements. The phenyl ethynyl-terminated hyperbranched poly（ether ether ketone） （HPOP-PEEK-PEP） was prepared by the end-capping approach. The HPOP-PEEK-PEP showed high glass transition temperature than HPOP-PEEK-F,but exhibited lower thermal stability. After cross-linking, the glass transition temperature, thermal stability and anti-chemical corrodibility of HPOP-PEEK-PEP were all improved.
