英文摘要A series of imide resins were prepared using 2,3,3,4-oxydiphthalic dianhydride, 4-phenylethynylphthalic anhydride, and aromatic diamines (1, 3-bis(3-aminophenoxy), 3,4-oxyaniline, 2,2-bis (trifluoromethyl) benzidine, and m-phenylenediamine) as starting materials. these imide oligomers were characterized by means of fourier transform infrared spectroscopy, differential scanning calorimetry, intrinsic viscosity measurements, and rheological measurements. some of these oligomers exhibited low (<1 pas at 250 degrees c) and stable (>2 h at 250 degrees c) melt viscosity, which was highly desirable for resin transfer molding process. thermosetting polyimides (pis) were then produced from these oligomers via thermal cross-linking reaction of phenylethynyl group. the properties of the thermosets were studied using tensile and flexural testing, dynamic mechanical thermal analysis, and thermogravimetric analysis. the cured pis exhibited a good combination of thermal and mechanical properties, with a tensile strength of 31-76 mpa, flexural strength of 38-142 mpa, glass transition temperatures of 233-358 degrees c, and 5% weight loss temperatures of 540-545 degrees c under nitrogen atmosphere.
