摘要:
Unsymmetrical azonitriles of the formula, ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently straight- or branched-chain alkyl having 1 to 7 carbon atoms or alkoxy substituted straight- or branched-chain alkyl having 2 to 11 carbon atoms but at least one of R.sup.1 and R.sup.2 and at least one of R.sup.3 and R.sup.4 must be different, have good efficiency as initiator for polymerizations or copolymerizations of vinyl monomers. These unsymmetrical azonitriles can be prepared by oxidizing a corresponding unsymmetrical hydrazo compound.
