Abstract

The four AB2 monomers, N-[3-or 4-bis (4-hydroxyphenyl) toluoyl]-4-chlorophthalimide and N- {3-or 4-[1, 1-bis (4-hydroxyphenyl)] ethylphenyl}-4-chlorophthalimides, were prepared and used for synthesis of hyperbranched poly (ether imide) s bearing hydroxyl end groups. These hyperbranched poly (ether imide) s had moderate molecular weights with broad distributions and showed glass-transition temperatures (T gs) between 177 and 230° C. ...
