  • Patent number: 4432889
    Abstract: A heterogeneous catalyst formed by the steps of:(a) irradiating an organic macromolecular substrate or a metal substrate with ionizing or U.V. radiation in the presence of a monomer selected from the group comprising o-, m-, or p- styryl diphenyl phosphine or o-, m-, or p- phenyl acrylyl diphenyl phosphine to graft the monomer to the substrate, and(b) reacting the graft copolymer with a homogeneous catalyst selected from the group consisting of catalytic metal salts and catalytic organometallic complexes such that the monomer-substrate conjugate becomes a ligand of the catalyst.These catalysts have particular activity in hydrogenation reactions, hydroformylation reactions, isomerization reactions, cracking reactions and dehydrogenation reactions of organic compounds.

  • Patent number: 4401688
    Abstract: The method for imparting permanent press characteristics to textile articles without using textile resins and textile resin catalysts includes applying to the textile article, a urethane acrylate prepolymer or an epoxy acrylate prepolymer or an acrylated polyester prepolymer or a water soluble monomer having a molecular weight less than 300 and selected from the group comprising acrylic acid, methacrylic acid, esters and substituted esters of acrylic acid and methacrylic acid and amides of acrylic acid and methacrylic acid, or prepolymers of such monomers, curing the prepolymer or monomer in situ on the textile article using ultraviolet radiation, and pressing the textile article along a crease after the application of the prepolymer or monomer. The pressing step may be applied either before or after the curing of the prepolymer or monomer.

  • Patent number: 4302522
    Abstract: A method of rendering a surface of substrate photoconduction comprising applying to the substrate a layer of N-vinyl carbazole and a prepolymer formed thereupon and completely polymerizing the monomer or prepolymer in situ on the substrate.

  • Patent number: 4268580
    Abstract: The invention relates to a radiation curable composition for coating onto leather. The composition comprises from 40 to 90% by weight of a first compound which is a prepolymer or co-prepolymers and from 60 to 10% by weight of a second compound which is mutually soluble with the first. The prepolymer or co-prepolymer is derived from monomer units of which at least 80% are an acrylate or methacrylate monomer and of which the balance, if any, may be styrene or its derivatives or isoprene. Preferably, at least 50% by weight of the prepolymer is butyl acrylate and up to 20% by weight is styrene. The second compound is one or more of urethane acrylate, epoxy acrylate; a rosin derivative; a monomer of vinyl chloride, vinyl acetate, vinylidene chloride or methyl methacrylate or copolymers of such monomers. The composition may be cured after coating onto leather by U.V. or electron beam radiation.

  • Patent number: 4183747
    Abstract: An electrophotographic recording element having a paper carrier, in which the paper carrier has been rendered slightly electrically conductive by being subject to a dose of ionizing radiation of from 10.sup.4 to 10.sup.8 rads.

  • Patent number: 4179401
    Abstract: A process for heterogenizing a metal salt or organometallic complex catalyst of the type containing a group VIII metal comprising the steps of radiation grafting a monomer having a .alpha. unsaturated bond to a metal or an organic polymer and complexing a nitrogen, halogen or phosphorous containing group to the monomer with the metal salt or organometallic complex. The resultant catalysts being useful in the hydrogenation, hydroformylation, isomerization, cracking or dehydrogenation of organic molecules.
