Abstract
Dialkyl diacyl peroxides in which the alpha carbon atom of one of the alkyl groups is secondary and substituted by chloro and alkyl. The compounds are useful as polymerization initiators of ethylenically unsaturated monomers such as vinyl chloride.
Claims14
In the polymerization of a monomer mass containing a monomer selected from vinyl chloride, ethylene, styrene, and methyl methacrylate and in the copolymerization of vinyl chloride and vinyl acetate by subjecting said monomers or comonomers to polymerization conditions in the presence of an initiating amount of organic peroxide, the improvement in which said organic peroxide includes a compound of the formula:
- ##STR3## where R and R.sub.1 are alkyl which together contain up to about 10 carbon atoms, and R.sub.2 is an alkyl group having up to about 18 carbon atoms.
