Abstract
Abstract The compounds according to the invention have the formula I ##STR1## in which R 1 , R 2 and R 3 are monovalent organic radicals or chlorine and Z is a tetravalent organic radical and A is a divalent organic grouping. These products are to be used as adhesion promoters, especially between inorganic solids and organic resins. 4 processes of preparation are given.
