    Abstract: A process for producing a carbonic diester by the catalytic reaction of carbon monoxide with a nitrous ester in the presence of a solid catalyst, characterized by adding a minute amount of a chloroformic ester to the feedstock gas comprising carbon monoxide and a nitrous ester, whereby the catalyst can be kept in a highly activated state for long and can provide the objective diester at a high reaction velocity and a high selectivity stably for long.

    Abstract: A novel polyimide wherein a tetracarboxylic dianhydride comprising 3,3',4,4'-biphenyltetracarboxylic dianhydride as the essential component is the starting tetracarboxylic dianhydride component, and an amine comprising between 0.5 and 30 mole percent of a diamine represented by the following general formula is the starting diamine component. (wherein A is a direct bond or a crosslinking group, and R1-R4 each represent a substituent). It is possible to obtain a polyimide, a polyimide film and a laminated body with an improved adhesion property and an improved moisture permeation rate, even without surface treatment, comprising, as the essential tetracarboxylic dianhydride, 3,3',4,4'-biphenyltetracarboxylic dianhydride which has conventionally only yielded polyimides with low adhesive strength.
