Abstract (en)

[origin: WO0216448A2] The invention relates to metallized unsaturated polymer anions, stabilized by a coordinate bond and having a large portion of cis double bonds. The invention further relates to a method for producing the same and to the use of said novel polymer anions in the production of graft polymers that are obtained by reacting the unsaturated polymer anions with anionically polymerizable nonpolar monomers. The graft polymers so obtained can be used for producing all sorts of shaped rubber bodies by corresponding vulcanization methods.
