| 中文摘要 | the four ab(2) 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 (tgs) between 177 and 230 degreesc. the thermogravimetric analytic measurement revealed the decomposition temperature at 5% weight-loss temperatures (t-d(5%)) ranging from 240 to 281 degreesc. analysis using h-1 nmr spectroscopy revealed the four types of hyperbranched poly(ether imide)s to have similar degrees of branching (ca. 60%). these polymers were modified by acylation or nucleophilic substitution reaction at the hydroxyl end groups. the conversion effectiveness depended on the type of modification reaction, modifier, and reaction conditions. the thermal stability and solubility of hyperbranched poly(ether imide)s were improved by the modification of the end groups. |
