Abstract
Abstract A nitrogen group containing silane of the formula ##STR1## where R is a C 1 -C 4 alkyl group which can contain an oxygen or sulfur atom in the chain, R' is a C 1-4 alkyl radical or hydrogen, A is a bivalent, saturated, branched or unbranched hydrocarbon radical having 2 to 4 carbon atoms in the chain and B is a bivalent, saturated, branched or unbranched hydrocarbon radical having 1 to 10 carbon atoms in the chain; the use of such compounds in an adhesive composition containing an organic polyaddition or polycondensation polymer as an adhesivizing agent.
