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