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.
