Abstract
In an improved adhesive process the amount of azidosilane coupling agent necessary to adhere a siliceous material to a polymer is reduced. The siliceous material, the azidosilane coupling agent and the polymer are admixed with an organosilicon compound and then heated at a temperature and for a time sufficient to decompose the azide groups of the azidosilane coupling agent. The reduction in the amount of azidosilane coupling agent is accomplished without adversely affecting the adhesion of the polymer to the siliceous material. Also disclosed are the products thus produced.
