  • Patent number: 5646226
    Abstract: A method for producing sucrose-based epoxy monomers having one to eight epoxy groups per molecule of sucrose, which comprises reacting a mixture comprising: a sucrose monomer having an allyl-containing group on at least one of the hydroxyl groups, and a reagent or catalyst selected from molybdenum, tungsten, vanadium, titanium and peracid, in the presence of hydrogen peroxide or a derivative thereof, in relative amounts sufficient to produce a sucrose-based epoxy monomer. Monomers thus produced are also provided. The sucrose-based epoxy monomers can be cured to produce a sucrose-based epoxy resin. Such resins are useful, for example, as adhesives, composites and coatings.

  • Patent number: 5612439
    Abstract: 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.

  • Patent number: 5510457
    Abstract: A method for preparing a processable polyisothianaphthene polymer includes steps of dissolving an isothianaphthene monomer in a solvent and introducing therein an initiator to initiate a polymerization reaction to produce a precursor of poly(dihydroisothianaphthene), dissolving thoroughly the precursor of poly(dihydroisothianaphthene) in the solvent in an appropriate ratio to obtain a poly(dihydroisothianaphthene) solution, proceeding a dehydrogenation reaction for the poly(dihydroisothianaphthene) solution by introducing a dehydrogenation agent to obtain a polyisothianaphthene microgel solution, and terminating the dehydrogenation reaction by introducing an inhibitor. This invention offers a simple, feasible, and economical way to prepare a large-area film with uniform film thickness, excellent stability, and good electrochromic, conducting, and mechanical properties.

  • Patent number: 5373068
    Abstract: Use of isophoronediamine isomer mixtures containing more than 40%, preferably more than 50 up to 70%, of the trans-isomer and less than 60%, preferably less than 50 down to 30%, of the cis-isomer as reactant in polyaddition resins selected from epoxy, polyurethane and polyurea resins. As curing agents in epoxy resins compared with previously known isomer mixtures, the isomer mixtures containing more than 40% of the trans-isomer and less than 60% of the cis-isomer unexpectedly lead to an extended pot life with simultaneously reduced maximum curing temperature and therefore reduced shrinkage problems. The isomer mixtures are also surprisingly suitable as amine components with reduced reactivity for the chain extension of polyurethane/polyureas.

  • Patent number: 5286808
    Abstract: Crosslinked elastomeric acetal polymers are made by the copolymerization of 1,3-dioxolane with a smaller amount of one or more bifunctional monomers. The two functional groups of the bifunctional monomer react under the same cationic polymerization conditions as the 1,3-dioxolane. The elastomeric acetal polymer does not crystallize even when the temperature is as low as -50.degree. C. The elastomeric acetal polymer is particularly useful for blending with crystalline acetal polymers to yield a composition with improved impact resistance.
