Curable composition having reactive silane-modified

The invention is a solvent- and water-free curable composition comprising at least one polymer A which is obtainable by reacting a polyether having at least one ethylenically unsaturated silane which carries at least one hydrolyzable group on the silicon atom, in the presence of a radical initiator. The invention further provides a process for preparing a solvent-free and water-free curable composition, characterized in that at least one polymer is prepared by reacting a polyether having at least one ethylenically unsaturated silane which carries at least one hydrolyzable group on the silicon atom, in the presence of a radical initiator and the polymer thus obtained is mixed with the other ingredients of the composition. Another object of the invention is the use of a curable composition according to the invention or a composition prepared by a process of this invention as an adhesive, sealant or coating material.
