Synthesis of aromatic poly(ether ketone)s having adhesion property to steel surface

摘要

Aromatic copoly(ether ketone)s composed of 5'-(2'-methyoxyphenylen)oxy-4-phenylenecarbonyl and 4"-phenylenoxy-4"- phenylenoxy-4-phenylenecarboyl units were successfully synthesized via P_2O_5-MsOH-mediated direct polycondensation of the corresponding carboxylic acids, i.e., 4-(2-methoxyphenoxy)benzoic acid and 4-)4-phenoxyphenoxy)benzoic acid. The aromatic copoly(ethe ketone)s bearing methoxy groups thus obtained have prominent adhesion property to steel surface with good thermal stability and high glass transition temperature.
