Abstract (en)
[origin: WO03062208A1] The present invention relates to novel onium imidazolide organometallic complexes which are cationic initiators of polymerization, and to the use of such novel onium salts for the polymerization or crosslinking of functional polymers or monomers by photochemical activation, or activation under an electron beam. The onium imidazolide had the formula (I): Q+ A- wherein Q+ is a onium cation. A is imidazolide anion of formula (II) [R13Mt-LN-MtR13]- wherein LN is imidazolide group, Mt is B, Ga, In or T1; R1 are identical or different and represent a monovalent aromatic hydrocarbon radical having from 6 to 14 carbon atoms with at least one electron-withdrawing element or group such as -CF3, -NO2 or -CN, or with at least two halogen atoms.
