Abstract
Abstract Compositions containing a radical-polymerizable olefinically unsaturated compound and a hydrazone of an aromatic aldehyde or ketone are provided. Also provided are methods for the production of such compositions and methods for the use of such compositions as an adhesive and sealing compound or its use for the coating and production of plastic moldings. The compositions polymerize radically at room temperature upon exposure to ambient air.
