The reactions of alkali metal salts of anthracene with alkyl halides result in the formation of 9,10-dialkyl 9,10-dihydroanthracenes as the principal product, although appreciable quantities of other adducts, notably the 1,2-and 1,4-dialkyl compounds, are also formed.

When a tetrahydrofuran solution of styrene or ~-methylstyrene (M) and anthracene (A) is reacted with alkali metal, anionic species are produced which can be titrated with alkyl dibromides (RBr2) to produce copolymers. These copolymers have been analysed structurally by NMR spectroscopy and by a mode
