Adhesivizing agent copolymers containing both acrylate or methacrylate groups and alkoxysilyl groups

摘要

The present invention relates to copolymers which can be used as adhesion mediating agents (adhesivers) between polymers and inorganic-oxide material. They are characterized by a reactive alkoxysilyl group and an acrylic or methacrylic acid moiety. Each of these two groups is linked to a fundamental constituent having two chain carbon atoms, this fundamental constituent being constructed on a compound having an ethylenically unsaturated group as monomer. The ratio of the alkoxysilyl groups to the acrylic or methacrylic acid esters in the new copolymers can be established as desired, for example by copolymerizing the copolymers with other compounds having ethylenically unsaturated groups, which do not have the above-named moieties. The present invention also relates to a method of preparing these new copolymers as well as intermediates which occur in the practice of this method, as formerly unknown products.
