| 英文摘要 | Copoly(phenylene-imide)s were synthesized by ni(0)-catalyzed coupling of aromatic dichlorides containing imide structure and 2,5-dichlorobenzophenone. the route offered the flexibility of incorporating different ratios of benzophenone and imide groups in the polymer backbone in a controlled manner. the resulting copolymers exhibited high molecular weights (high inherent viscosity), and a combination of desirable properties such as good solubility in dipolar aprotic solvents and cresols, film-forming capability and good mechanical properties. wide-angle x-ray diffractograms revealed that the polymers were amorphous. these copolymers had glass transition temperatures between 209 and 319 degrees c and 10% weight loss temperatures in the range of 502-543 degrees c in nitrogen atmosphere: the tough polymer films, obtained by casting from n-methylpyrrolidone solution, had a tensile strength range of 83-156 mpa and a tensile modulus range of 1.6-3.6 gpa.
