Asymmetrical organic diacyl peroxide polymerization initiators having enhanced initiator efficiency and characterized by the presence of an acyclic acyl group of four or more carbon atoms having bromo or halo substitution at the alpha carbon atom, the other acyl group being different and heterosubstituted. However, when the alpha-halosubstituted acyl group is branched chain the other acyl group may be hydrocarbon.

引发剂,其特征在于存在具有α-
溴或卤素取代的四个或更多碳原子的无环酰基,另一个酰基是不同的且杂原子取代的。然而,当α-卤素取代的酰基是支链时,另一个酰基可以是碳氢化合物。
