Abstract

Compounds of the formula <FORM:1044757/C2/1> where A, A1 are each -CH2-CH2-, -CH = CH-, or -C = C- radicals; R1, R2, R3, R4 are C1- 3 alkyl radicals; are prepared by reacting a diol of the formula <FORM:1044757/C2/2> with a dihydroperoxide of the formula <FORM:1044757/C2/3> in the presence of solvents such as a hydrocarbon or chloroform and a catalyst such as perchloric acid. Suitable diols may be obtained by the reaction of acetylene, methylethylketone, or methylisopropylketone in the presence of KOH, the product being hydrogenated if desired to the corresponding alkane and alkene diols. The diols may be oxidized to dihydroperoxides by hydrogen peroxide in sulphuric acid.ALSO:Polyolefin foaming compositions include, with or without other peroxides, at least one compound of the formula <FORM:1044757/C3/1> where A and A1 are each one of the groups -CH2-CH2-, -CH = CH-, and -C­C-; and R1, R2, R3, R4 are C1- 3 alkyl radicals. Specified polymers include low and high density polyethylene and a copolymer of ethylene and vinyl acetate. Exemplified blowing agents are dinitrosopentamethylene tetramine, azodicarbonamide and diphenyloxide-4,41-disulphohydrazide. Carbon black, graphite, and metal oxides, carbonates, silicates and phosphates may be used as fillers.
