Heterocyclic alkoxyamines as regulators in controlled radical polymerization processes |
摘要 |
The present invention is aimed at a process for controlled polymerization of ethylenically unsaturated monomers in the presence of heterocyclic sterically hindered alkoxyamine compounds. The intermediate N-oxyl derivatives, a composition of the N-oxyl derivatives with ethylenically unsaturated monomers and a free radical initiator, as well as a process for polymerization are also subjects of the present invention. Still further subjects of the invention are novel amine precursors and a novel process for manufacturing 5-ring heterocyclic amines.
