Azo free radical initiators containing hindered amine moieties with low basicity

摘要

Compounds which contain azo linkages as well as a hindered amine light stabilizer moiety of low basicity function as free radical polymerization initiators and provide a polymer containing a hindered amine stabilizer chemically bonded to said polymer. The low basicity of the instant compounds prevents interaction with acid catalysts used in some polymerization systems.
