✦ Synopsis

A~tract~opolymers ofcyclohexene and cyclohexa-l,3-diene with sulphur dioxide have been prepared [poly-l,2-(cyclohexane)sulphone and poly-l,4-(cyclohexa-2-ene)sulphone, respectively], and a study made of their aromatization. It was found that the latter copolymer only could be partially aromatized by using bromine-sulpholane, sulphur-dimethylformamide or selenium dioxide--decalin. The properties of the polymers are discussed in relation to the proportion of aromatic character. The scope and limitations of introducing aromatic rings into a polymer chain, by an addition polymerization of cyclohexyl derivatives followed by dehydrogenation, are discussed.

Blends of poly(hydroxyether of phenolphthalein) (PHP) with poly(ether sulphone) (PES) were prepared by casting from a common solvent; they were found to be miscible and show a single, composition-dependent glass transition temperature. All the PHP/PES blends exhibited lower critical solution tempera
