ABSTRACT:
9,9-Bis(3,5-diphenyl-4-hydroxyphenyl)fluorene a novel compound can be used to produce amorphous poly(arylene ethers) which have high glass transition temperatures and good thermo-oxidative stability and which are soluble in aromatic and chlorinated solvents; the novel fluorene derivative is produced by transalkylation of 9,9-bis(4-hydroxyphenyl)fluorene or 9,9-bis(4-methoxyphenyl)fluorene with 2,6-diphenylphenol.
