Abstract: The crosslinkable trifluoromethylated poly(aryl ethers) terminated with phenylethynyl moieties(11F-PAE-PEP)s were prepared in two step syntheses.The structure of 11F-PAE-PEP was confirmed by FTIR and 1HNMR.The crosslinking behavior was studied by DSC.There is a remarkable increase of Tg after crosslinking of the poly(aryl ethers).The Tg values of crosslinked polymers were 437 and 446K, respectively.The crosslinked polymers could not be soluble in common organic solvents, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-2-pyrrolidinone, chloroform, and tetrahydrofuran.The temperatures at a 5% mass loss of the crosslinked polymers in air were above 789 K.They showed a good optical property, too.This kind of polymers will be the promising materials used as the microelectronics and optical waveguide devices.

Key words: Poly(aryl ether), Fluorinated polymer, Cross-linkage
