I. A novel class of compounds X.sub.n --R.sub.p --Y.sub.m where R is a 2-4 valence aliphatic, cycloaliphatic or aromatic radical, X is an acylating function; Y is a peroxy containing group and n and m are each equal to 1-2 and p is at least 1. Ii. a novel class of polymers [A.sub.n -(R-D.sub.n).sub.n ].sub.v -P.sub.w -Z where A is a peroxy containing group; R is a 2-4 valence aliphatic, cycloaliphatic or aromatic radical, P is a polyvalent polymeric residue; D is a carbonyl containing connecting group; Z is H, OH, NH.sub.2, NHR.sub.2, SH or R.sub.2 O group; v and w are each equal to 1-100; and n is equal to 1-2. Iii. polymers II are useful with vinyl monomers in the formation of block and graft polymers. Iv. peroxides having an acylating function are prepared by reacting at 0.degree.-80.degree. C an organic peroxide having an hydroxyl or carboxyl group with a defined acylating reactant. V. peroxides having at least one acylating function are prepared by peroxidizing a compound having at least two acylating functions as the only peroxidizable substituents.
