Fluoro-terminated hyperbranched poly(aryl ether ketone)(HPOP—PEEK—F)with 4-phenoxyphenyl side groups was prepared from A2(2-(4-phenoxyphenyl)-1
4-diphend)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 and1H-NMR.The degree of branching(DB) of HPOP-PEEK—F was 0.66 determined by1H-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 eorrodibility of HPOP—PEEK—PEP were all improved.
