    摘要: Novel functionalized peroxides which may be used as crosslinking, grafting and curing agents, initiators for polymerization reactions and as monomers for condensation polymerizations to form peroxy-containing polymers, which in turn can be used to prepare block and graft copolymers, have the following Formula I: ##STR1## R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, X, Y.sup.1, Y.sup.2, Y.sup.3, Z.sup.1, Z.sup.2, x, y and z are as defined in the Summary of the Invention. The compounds of Formula I may be prepared by reacting hydroxy-containing tertiary hydroperoxides with diacid halides, phosgene, dichloroformates, diisocyanates, anhydrides and lactones to form the functionalized peroxides. These reaction products may be further reacted, if desired, with dialcohols, diamines, aminoalcohols, epoxides, epoxy alcohols, epoxy amines, diacid halides, dichloroformates and diisocyanates to form additional functionalized peroxides.

    摘要: A process for generating random dialkyl or alkyl aryl peroxide functionality on elastomers is disclosed. Generally, the process involves dissolving an elastomer in a solvent followed by treating the resulting solution with an oxidizing agent in the presence of a catalyst. In a preferred embodiment, the oxidizing agent is a an alkyl or aryl hydroperoxide and the catalyst is a Group VIIa, VIII, Ib or IIb metal.

    摘要: A process for preparing .alpha.-methylstyrene/acrylonitrile copolymers by suspension or bulk polymerization of .alpha.-methylstyrene and acrylonitrile with or without other vinyl compounds such as styrene, methyl methacrylate, vinyl toluene and t-butylstyrene in the presence of a difunctional organic peroxide, preferably a difunctional organic peroxide having a 10 hour half-life temperature of 60.degree. to 110.degree. C., at a polymerization temperature of 80.degree. to 120.degree. C. The process produces the copolymers having excellent transparency, heat resistance and strength in high conversions in a short time.
