摘要
Two novel poly(aryl ether ketone)s based on (3 methyl)phenylhydroquinone were synthesized via aromatic nucleophilic substitution reaction. The high molecular polymers were easily obtained because of the high reaction activity of bisphenol monomer. The traces of DSC showed that the T gs of m TPEEK and m TPEEKK were 421 and 432 K, respectively. The two polymers exhibit a high thermal stability and good solubility. The transparent and flexible films were readily prepared with chloroform solution. The film of m TPEEK had a low dielectric constant( ε =2 7).
