    摘要： Heat resistant resin compositions consisting essentially of 5-95 wt.% of polyimide composed of recurring units represented by the formula (I):
    wherein X and Y are the same as defined in the claims, and 95-5 wt.% of known aromatic polyetherimide are disclosed.
    The resin compositions of this invention have good thermal stability in the high temperature region, particularly in the temperature range of 300-400°C. The compositions can be injection molded due to the retention of frictional property in aromatic polyetherimide and also have thermal resistance, impact resistance and abrasion resistance. Therefore the compositions can be widely used as the material of parts in any industrial fields such as automotives, business machines, electric and electronic appliances, automatic energy saving devices, aeronautics and space instruments and general purpose industrial machines, which renders this invention very valuable.

    摘要： A process for producing continuously an aromatic polycarbonate oligomer by reacting an aromatic dihydroxy compound and an alkali metal base or an alkaline earth metal base with a carbonyl halide compound comprises:
    (1) feeding continuously to a tank reactor an aromatic dihydroxy compound, water, a molecular weight controlling agent, a polymerization catalyst, a carbonyl halide compound, and an organic solvent, and an alkali metal base or an alkaline earth metal base in an amount of 1.15 - 1.6 equivalents based on the aromatic dihydroxy compound, (2) carrying out the reaction with a residence time as defined by the following formula, log Y (0.0005 ≦ X
    where X is an amount of the polymerization catalyst in terms of mole % based on the amount of mole of the aromatic dihydroxy compound fed per unit time, and Y is a residence time (min.), and (3) continuously withdrawing the reaction mixture from the tank reactor to obtain an aromatic polycarbonate oligomer having a number average molecular weight of 1,000 - 10,000. An aromatic polycarbonate is produced by polycondensation of the aromatic polycarbonate oligomer.
