Procedure

To 3.24 g of [3-[2-[4-[bis (2-hydroxyethyl) amino]phenyl]ethenyl] 5,5-dimethyl-2-cyclohexene-1-ylidene]-N,N'diethylthiobarbiturate and 2.93 g of hexafluorobisphenol A bischloroformate in 100 ml of THF (tetrahydrofuran) there was added dropwise in one hour 1.02 ml of pyridine, at 0° C. The reaction mixture was allowed to heat up to 20° C. After eighteen hours of stirring, the reaction product was precipitated in methanol. M.W.: 9,900, the Tg was measured to be 142°-148° C.
