  • Use of deaminatively-generated carbocation as polymerization initiators
    Patent number: 6602967
    Abstract: Deaminatively generated carbocations to initiate addition polymerization are disclosed. The high reactivity of the carbocation allows initiation of polymerization with virtually all alkenes, alkynes, alicyclic and aromatic monomers, regardless whether multisubstituted or conjugated. In addition, the carbocation initiates a polymerization reaction that generates an extremely high molecular weight polymer. In particular polystyrene of viscosity average molecular weight of approximately 106 was obtained.
