YieldReaction ConditionsOperation in experiment
In 1-methyl-pyrrolidin-2-one; at 100 - 350℃; for 1h; Example 5; Synthesis of imide oligomer by Using 4-phenyl ethynyl phthalic anhydride Obtained in Example 3 and Comparative Examples 1 to 3 as Terminal End Groups; In accordance with the method as described in Non-Patent Document No. 2, a solution of an amide-acid oligomer having an average molecular weight of about 9,000 was prepared from the 4-phenyl ethynyl phthalic anhydrides obtained in Example 3 and Comparative Examples 1 to 3, and 3,4'-oxydianiline and an N-methylpyrrolidone solution of 4,4'-oxydiphthalic anhydride. The thus-prepared amide-acid oligomer was centrifuged, applied, dried and subjected to thermal treatments for one hour at 100° C., 225° C. and 350° C. in this order, to thereby obtain films of cross-linked imide oligomer. On the other hand, toluene was added to an N-methylpyrrolidone solution of the amide-acid oligomer and, the mixture was subjected to the steps of azeotropic dehydration, cooling, filtration, rinsing with water and methanol in this order, and drying, to thereby isolate an imide oligomer. Tg and kinetic properties at 23° C. of each film prepared in accordance with the above-described method corresponding to 4-phenyl ethynyl phthalic anhydrides obtained in Example 3 and Comparative Examples 1 to 3 were measured in accordance with a method as specified in ASTM D882 and, also a temperature at which 5percent by mass of the imide oligomer was reduced was measured by using a thermobalance. These results are shown in Table 1.
