反応手順

10 mmol of 2,5-dimethylhydroquinone in 25 mL of chlorobenzene, 20 mmol of 1-bromo-5,8,11-trioxadodecane, 20 mmol of sodium hydroxide in the form of a 50% aqueous solution are reacted in the presence of a phase transfer catalyst, tetrabutylammonium bromide. The 1,4-dimethyl-2,5-bis(5,8,11-trioxadodecyloxy)benzene thus obtained is purified by chromatography. 1,4-bis(Bromomethyl-2,5-bis(5,8,11-trioxadodecyloxy)benzene is obtained by treatment with two equivalents of N-bromosuccinimide. Duplicative elimination by potassium tert-butoxide in THF gives the polymer.
