ABSTRACT:
Compositions are prepared by reacting one mol of a bis-imide of the formula: ##EQU1## with at least one mol of an amino-silane of the formula: ##EQU2## IN WHICH R represents a divalent hydrocarbon radical with 2 to 20 carbon atoms which is free from unsaturated bonds other than aromatic bonds, a divalent mono- or bis-heterocyclic radical with 2 to 10 carbon atoms, or a divalent organic radical with 4 to 20 carbon atoms which consists of more than one said divalent hydrocarbon radical bonded to one another via --O--, --S--, --CO-- or --SO.sub.2 --, R' represents a divalent hydrocarbon radical with 1 to 20 carbon atoms or a divalent radical with 4 to 20 carbon atoms which consists of more than one hydrocarbon radical bonded to one another via --NH-- or --O--, Z represents a hydrolysable group, R" represents a monovalent radical with 1 to 6 carbon atoms and x is 0 or 1. These compositions are particularly useful, especially as solutions, as undercoats for adhering organopolysiloxane compositions to a variety of substrates.
