    摘要: Novel N-(haloalkyl)sulfonyl imides represented by the formula ##STR1## are prepared by the reaction of a 2-alkyl- or 2-aryl-oxazoline or oxazine with an arylene or alkane sulfonyl halide. In the formula for the novel sulfonyl imide, R.sub.1 and R.sub.2 are each independently C.sub.1 -C.sub.20 aryl, alkaryl or alkyl groups; R.sub.3, R.sub.4 and R.sub.5 are each hydrogen or methyl groups; n is the integer 0 or 1 and X is a chloro, bromo or iodo group. These novel sulfonyl imides are particularly useful in the preparation of N-(2-chloroethyl)- and N-(3-chloropropyl)sulfonamides.

For example, a compound of the formula ##STR3## is polymerized with an azobis(isobutyronitrile) catalyst to form addition polymers of the repeating unit ##STR4## When cross-linked, rendering it water-insoluble, such an addition polymer concentrates an aqueous solution of sodium chloride when contacted with same at about 0.degree.

    摘要: In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.

    摘要: An electrically conductive polymer is comprised of the reaction product of a dendrimer and an electrophoric compound which exhibits .pi.-stacking upon reduction. The reaction product which is a peripherally modified dendrimer is formed and reduced, either chemically or electrochemically, in a polar solvent. The reduced electrophoric moieties aggregate (form .pi.-stacks) to form electrically conductive pathways. The reduced peripherally modified dendrimers of the invention can be cast into films and other solid forms to provide flexible electrical conductors and semiconductors. The conductive polymers of the invention exhibit electrical conductivities comparable to that of doped polyacetalene, but are oxygen and moisture stable.

    摘要: Ion exchange resins and chelate resins are provided with ion exchange or chelate capability by depositing on an insoluble substrate dense star polymers having terminal group densities greater than conventional star polymers exhibiting greater and more uniform reactivity than their corresponding conventional star polymers. For example, a third generation, amine-terminated polyamidoamine dense star polymer prepared from ammonia, methyl acrylate and ethylenediamine having 1.24.times.10.sup.-4 amine moieties per unit volume (cubic Angstrom units) in contrast to the 1.58.times.10.sup.-6 amine moieties per unit volume contained by a conventional star polymer can be reacted with a chloromethylated styrene/divinyl copolymer (insoluble substrate) to form a desirably weak base anion exchange resin.
