Reaction mixtures, processes for their preparation and their use as polymerization initiators

摘要

Mixtures obtained by reaction of an alpha -arylketone or of an arylaldehyde and the equivalent amount of a base metal in an inert aprotic solvent with a di-, tri- or tetrachlorosilane or a chlorinated polyorganosilane or -siloxane work as initiators for free radical-initiated polymerization reactions.
