Abstract

Nanosized palladium species, which were prepared in situ from Pd(OAc) 2, PPh 3 and Bu 4 NOAc in 1,4-dioxane, were suitable for the synthesis of 1,1′-binaphthyl-2,2′-dioxy-bearing aromatic poly(ether ketone)s 5. The resulting poly(ether ketone)s 5 are soluble in typical organic solvents, such as CHCl3, tetrahydrofuran and N,N-dimethylformamide. Glass transition temperatures (Tgs) of poly(ether ketone)s 5 are in the range of 188-224 °C. Temperatures where 10% weight losses of poly(ether ketone)s 5 occur under N2 flow are in the range of 445-480 °C.
