EXAMPLE - 2,2'-(3,4-Dihydro-2H-thieno(3,4-b)(1,4)dioxepine-3,3-diyl)diethanol and tetrahydrofuran (THF) were first introduced into the dried flask and then reacted with sodium naphthalene in THF. Then ethylene oxide was introduced to the flask and polymerized at 40 degrees C for 3 days. The precipitated macromonomer was collected by filtration to give alcohol compound of formula (2a) (where a is not defined). (2a) and acetyl chloride was mixed in dried THF in the presence of sodium hydroxide aqueous solution. The reaction mixture was kept for 6 hours at 50 degrees C. The reaction mixture was poured into n-hexane/ether (1:1 v:v). The precipitates were filtered to give ester compound of formula (3a). Bromination was performed by conventional method using N- bromosuccinimide in the presence of acetic acid. The resultant product was purified by re-precipitation in n-hexane to give 6-bromo-3,4-dihydro-2H-thieno(3,4-b)(1,4)dioxepine compound of formula (4a). Deprotection of acetyl group was performed in THF solution with a trace amount of hydrochloric acid solution (0.1 N). Acetyl group was removed to yield to give alcohol compound of formula (5a). It was purified by re-precipitation into ether and ethanol. 2-(2-(5-Bromothiophen-3-yl)ethoxy)ethanol was dissolved in dried tetrahydrofuran and (5a) was also dissolved in the mother mixture with a trace amount of lithium diisopropylamide at -40 degrees C. 1,3-Bis(diphenylphosphino)propane dichloronickel (II) can be used as a catalyst. The product was poured into ethanol. The solid was filtered to be dried under vacuum for 2 days at 80 degrees C to give 3,4-dihydro-2H-thieno(3,4-b)(1,4)dioxepine unit containing polymer of formula (Ia).
