    摘要： A process for coating inorganic substrates, especially metallic or metalloid substrates, sintered metal carbides and carbon materials with carbides, nitrides and/or carbonitrides, using certain nitriles as sources of carbon and nitrogen, is described. High deposition rates and smooth coatings of good to very good adhesion are achievable by this process.

    摘要： A process for producing polyamide-polyamide-acid copolymers having an inherent viscosity of from 0.1 to 2.5 and cyclized derivatives thereof is disclosed, which process comprises reacting a polyamide-acid block having an average molecular weight of from 750 to 20,000 with a dicarboxylic acid dichloride and a diamine. The resultant polyamide-polyamide-acid copolymers are distinguished by good processing characteristics as well as good electrical, thermal and/or mechanical properties.

    摘要： New silicon-modified polyamide, polyamide-acid and polyamide-amide-acid prepolymers are described, which can be manufactured, for example, by reaction of aminosilanes with suitable polyamides, polyamide-acids or polyamide-amide-acids. These prepolymers are suitable for the manufacture or cross-linked polymers containing siloxane groups, which possess good mechanical, electrical and thermal properties.
