<p>The compounds according to the invention are polymers, containing imidyl groups and silyl groups, of the formula in which Yl snd Y2 are Si-organic radicals, a is an in teger from 1 to 50 and Z, Zl and Z2 independently of one another are each divalent organic radicals, but at least one of the radicals Zl and Z2 is a group which contains an ausubtituted or substituted imidyl group. The products according to the invention may be prepared, for example, by a multi-stage reaction of mphenylenediamine, 5 dimethylmaleimidyl-lsophthalic acid dichloride, 3,3'-4,4'-benzophenonetetracaboxylic acid dianhydride and Y-aminopropyl-di-n-propoxymethylsilane in solution The products are used as adhesion promoters, for example between inorganic solids and organic resins</p> |
