Examples are given in which ethylene-propylene copolymers are vulcanized.ALSO:Alkylidene peroxides of the general formulae wherein R and R1 are each H, alkyl, aryl or aralkyl groups, R11 and R111 are each tertiary alkyl or tertiary aralkyl groups, R1111 is a hydrogen atom or an alkyl radical, R5 is an alkylene, arylene or aralkylene radical and R6 is the same as R11 or R111, R11 and R111 are different and n is 0 or 1 are prepared in the case of the first three types by transperoxidation of an alkylidene peroxide of the formulae with a hydroperoxide of the formula R111OOH which is less volatile than the hydroperoxide R11OOH from which the radical -OOR11 is derived, in the absence of catalysts generally at from 35 DEG to 110 DEG C. by continuously removing by distillation the hydroperoxide R11OOH released generally until 1 mol. of hydroperoxide R11OOH per 1 mol. of starting alkylidene peroxide has been eliminated or until the R11OOH hydroperoxide has been completely eliminated; and in the case of the fourth type by transperoxidation generally of 2 mols of an alkylidene peroxide of the formula with 1 mol. of a dihydroperoxide of the formula This invention also comprises the compounds of the formulae per se: Examples are given for the production of the compounds. They are useful as vulcanizing agents.

摘要： A new class of compounds: R-W-R'' where R and R'' are identical oxy radicals containing peroxide functions such as dialkyl or diaralkyl peroxide, peroxyketal, peroxyester, or monoperoxycarbonate, and W is a carbonyl group, or carbonyl containing group, or an alkylidene or aralkylidene group, or a phosphorus containing group. Examples: Di(1,3-dimethyl-3-(t-butylperoxy)butyl) carbonate; Di(1,3-dimethyl-3-(n-butoxycarbonylperoxy)butyl) carbonate; 2,2-Bis(3,3-di(t-butylperoxy)butoxy)propane; Di(1,3-dimethyl-3-(t-butylperoxy)butyl) ethyl phosphate. They are free radical affording compounds useful in crosslinking of polyolefins and unsaturated polymers, and for the polymerization of vinyl monomers and diolefinic monomers.

摘要： 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.
