Mixtures of azolakanes of varying thermal stabilities at least one of which is an unsymmetrical azoalkane (R--N.dbd.N--R'), are prepared by reacting 4 equivalents of a mixture of two or more primary alkyl, cycloalkyl or aralkylamines with 1 equivalent of sulfuryl chloride in an inert solvent and oxidizing the resulting mixture of sulfamide products with basic bleach. The unsymmetrical azoalkanes can be separated from the symmetrical azoalkanes by a variety of conventional techniques. The azoalkane mixtures are excellent polymerization initiators for vinyl monomers and curing agents for unsaturated polyester resins.
