Abstract
This invention relates to novel reactive amino or hydrazino peroxides (hereinafter generally referred to as "AHP's") and derivatives all having a Structure A: ##STR1## in which the definitions of P, R11, R22, X, Q and x, y and z are given in the Summary Of The Invention section, for example, 4,4-di-(t-butylperoxy)pentanohydrazide (I-1), and the use of these novel compounds in curing unsaturated polyester resins, in initiating polymerization of ethylenically unsaturated monomers, for modifying rheology, for crosslinking and curing olefin polymers and elastomers, for producing novel graft and block copolymers, and for producing novel polymers with covalently bound performance additive functions.
