Abstract
Soluble and/or meltable benzothiazole-containing polyaryl ethers with a glass transition temperature of above 150.degree. C. and a melting point of up to 450.degree. C. are composed essentially of repeat units of the formula I ##STR1## whose rings may be substituted by C.sub.1 -C.sub.6 -alkyl, C.sub.1 -C.sub.6 -alkoxy, aryl or halogen and where R is ##STR2##
