ABSTRACT:
New aliphatic azo compounds containing an .alpha.-hydroperoxy group and the alkali metal and alkaline earth metal salts thereof as represented by the general structure ##STR1## processes for preparing I where M is H and R is t-aliphatic by reacting t-aliphatic azo compounds having an .alpha.-halo substituent with about an equimolar amount of sodium or hydrogen peroxide; processes for converting I where M is H to its alkali or alkaline earth metal salt by reaction with aqueous solutions of the corresponding base or with calcium or sodium hydride; and the use of these novel compounds as polymerization initiators for vinyl monomers and as curing agents for resins. For example, 2-t-butylazo-2-hydroperoxy-4-methylpentane is prepared from sodium peroxide and 2-t-butylazo-2-chloro-4-methylpentane and used to polymerize vinyl chloride and to cure unsaturated polyester resin.
