Abstract
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.
