Tertiary-aliphatic alpha-peroxyazo compounds represented by the structure ##STR1## processes for preparing these compounds by reacting ##STR2## with salts or salt solutions of HOOH (III), (r").sub.3 cooh (iv), ##STR3## 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-(t-butylperoxy)-propane is prepared by reacting the potassium salt of t-butyl-hydroperoxide with 2-t-butylazo-2-chloropropane; and the product is used to cure unsaturated polyester resin at room temperature and to polymerize vinyl chloride at 20.degree.-30.degree. C.
三级脂肪基α-过氧基偶氮化合物的结构式为##STR1##,制备这些化合物的过程是通过将##STR2##与HOOH(III)、(r").sub.3 cooh (iv)、##STR3##的盐或盐溶液反应,以及这些新型化合物作为乙烯单体的聚合引发剂和树脂的固化剂。例如,2-叔丁基偶氮基-2-(叔丁基过氧基)-丙烷是通过将叔丁基过氧化氢的钾盐与2-叔丁基偶氮基-2-氯丙烷反应制备的;并且该产品可用于在室温下固化不饱和聚酯树脂,并在20℃-30℃下聚合氯乙烯。
