    摘要： An electronic circuit having an electrically conductive pattern formed on a substrate and having on at least one surface of the substrate a film obtained from a soluble polymerizable oligomer of the formula: ##STR1## wherein D is ##STR2## wherein M is --C.tbd.C--, --C.tbd.C--C.tbd.C, --O--, ##STR3## wherein R is an alkyl or aromatic group; wherein Ar is an aromatic group; wherein x is an integer greater than two but less than 30, z is either zero or an integer, and y is an integer wtih the sum of y and z equal to x; and wherein n is an integer from 1 to 10. The substrate is coated by applying the above composition to the substrate and then hardening the composition by further polymerization. Preferred compositions contain the above described oligomer and certain plasticizers and/or toughening agents.

    摘要： A process for coating a substrate to provide good planarization and good mechanical and thermal stability, the process comprising applying to the substrate an amino-terminated oligomer and an ester, with the oligomer being formed from an aromatic diamine and from an aromatic dianhydride, and the ester being formed from an aromatic tetracarboxylic acid and an alcohol, and by reacting said oligomer and said ester in situ, with the process being characterized in that the ester reacts with an amine group of the oligomer to form a high molecular weight polyamide at a temperature between 40.degree. C. and 140.degree. C., and continues to react to form a cyclic imide.

    摘要： Boron nitride-boron nitride composite bodies may be produced by combining pure boron nitride fibers with partially nitrided fibers consisting essentially of B, N, O, and H, and hot pressing the composite at elevated temperatures and pressure. The partially nitrided material serves as a source of matrix material for the boron nitride fibers, and when fiber orientation is properly controlled, bodies of extremely high strength may be obtained. Densities in excess of 1.5 g./cc. may be obtained, in a one-step process which overcomes difficulties inherent in multiple-step nitriding and re-nitriding processes.
