Abstract A novel class of compounds Xn-Rp-Ym 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. A novel class of polymers ((An-(R-Dn)n)v-P)w 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, NH2, NHR2, SH or R2O group; v and w are each equal to 1-100; and n is equal to 1-2. Polymers II are useful with vinyl monomers in the formation of block and graft polymers. Peroxides having an acylating function are prepared by reacting at 0*-80* C an organic peroxide having an hydroxyl or carboxyl group with a defined acylating reactant. Peroxides having at least one acylating function are prepared by peroxidizing a compound having at least two acylating functions as the only peroxidizable substituents.

A method of preparing a peroxide having a haloformate function with method comprises: reacting an organic peroxide having at least one hydroxyl group, said hydroxyl group being the only group in said peroxide capable of reacting with the haloformate forming reactant; with a haloformate forming reactant CO(B)2, where B is selected from Cl and Br; at a temperature between about 0* C and 80* C., the maximum temperature being controlled to avoid substantial decomposition of the peroxy groups present in the reaction zone.
