Cobalt(II) chelates as chain transfer agents in free radical polymerizations

摘要

Free radical polymerization processes employing cobalt (11) chelates of vicinal iminohydroxyimino compounds, diazadihydroxyiminodialkyldecadienes and -undecadienes, tetraazatetraalkylcyclotetradecatetraenes and -dodecatetraenes, N,N'-bis-(sali^qylidene) ethylenediamines and dialkyldiazadioxodialkyldodecadienes and -tridecadienes as catalytic chain transfer agents for controlling the molecular weight of the homopolymers and copolymers produced.
