    摘要: Novel peroxydicarbonates are provided in which the alkyl carbonate moiety is 2-alkyl-2-phenyl substituted. The compounds are useful as polymerization initiators of ethylenically unsaturated monomers, such a vinyl chloride, and as catalysts of unsaturated polyester resins. The subject peroxydicarbonates are characterized in that they are solid at room temperature, have ambient temperature stability in spite of a low 10 hour half-life temperature, and can normally be transported and stored without refrigeration.

    摘要: Novel mono and di peroxyesters characterized by chloro-substitution of a tertiary carbon atom at the alpha position relative to the carbonyl group(s), the monoperoxyesters having no less than 9 carbon atoms and the diperoxyesters having no less than 16 carbon atoms, are utilized as polymerization initiators. Typical is the polymerization of styrene and the copolymerization of vinyl chloride and vinyl acetate.
