Unsymmetrical azo compounds (R").sub.3 C--N.dbd.N--R' where (R").sub.3 C-- is tert.-aliphatic and R' is --C(R.sub.1)(R.sub.2)(Z) or ##STR1## e.g., 1-t-butylazo-1-chlorocyclohexane, their use as vinyl polymerization initiators and polyester resin curing agents, and methods for preparing same from t-aliphatic hydrazones and t-aliphatic .alpha.-halo-substituted azoalkanes.
