    Abstract: A method of making a polymeric compound, comprising discrete particles responsive to an external stimulus, that is resistant to aggregation in high-shear fields, which includes the addition of a polymerization initiator to a reaction mixture comprising a monomer corresponding to the polymeric compound, wherein the method comprises the portion-wise addition of aliquots of a cross-linking agent to the reaction mixture, wherein an aliquot of the cross-linking agent is added to the reaction mixture both before the addition of the polymerization initiator and after the polymerization has progressed substantially to completion. The polymer particles are largely immune to the effects of transient shear rates at least as high as 106 s?1, whilst maintaining their thermal responsiveness and being present at moderate concentration. The structural and chemical modifications brought by the delayed portion-wise addition of the cross-linking agent allow an improvement in stability in a high-shear field.

    Abstract: The present invention concerns treated fibrous porous material having a defined nanostructure comprising reactive sites thereon, wherein said fibrous porous material is treated with a low viscosity organic solution comprising organic solvent, isocyanate component unsaturated resin and optionally additional additives. The treated fibrous porous material is further mixed with a resin to form a composite. The composite may be formed by various methods of mixing and molding. The invention is further directed to various composites made therefrom. The fibrous porous material is selected from the group comprising cellulose, lignin, synthetic ceramics, porous metal nanopowders, kaolin, bio fibers and porous powders of biological origin or their mixtures.

  • Patent number: 6831115
    Abstract: Modified polyolefins are produced by reacting a functionalized polyolefin with one or more ethylenically unsaturated compounds having a functional group reactive with the functional group on the polyolefin. These modified polyolefins may then polymerize in the presence of a photoinitiator upon exposure to ultraviolet radiation and also have the capability of copolymerizing in the presence of a photoinitiator with other ethylenically unsaturated crosslinking agents upon exposure to ultraviolet radiation. These modified polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines, and therefore may be rendered water-dispersible. The modified polyolefins of the present invention significantly improve the adhesion of paints, inks, and adhesives to various plastic and metal substrates.

  • Publication number: 20040167283
    Abstract: Disclosed are linear polyphosphonates produced by a transesterification process. These linear polyphosphonates exhibit a unique and advantageous combination of properties, such as outstanding fire resistance, unexpectedly high Tg's and good toughness at a low molecular weight. The favorable processing characteristics (such as low melt viscosity and excellent melt stability) of these linear polyphosphonates enable economic processing. Also disclosed are polymer compositions that comprise these linear polyphosphonates and at least one other polymer, wherein the resulting polymer compositions exhibit flame retardant properties. Further disclosed are articles of manufacture produced from these polymers, such as fibers, films, coated substrates, moldings, foams, fiber-reinforced articles, or any combination thereof, these articles may be coated with a moisture barrier to enhance their moisture resistance properties.

  • Patent number: 6716927
    Abstract: Amines having an unsaturated bond can be introduced into the organic layer of organic-inorganic laminar perovskite compounds comprising a metal halide and an organic amine, and the organic layer can be polymerized by applying external energy such as by irradiating with UV light or radiation. In this way, the quantum well structure is stabilized. The organic-inorganic laminar perovskite polymer compound is produced by cross-linking unsaturated bonds of an organic-inorganic laminar perovskite compound represented by the general formula (RNH3)2MX4 (in the formula, R is a hydrocarbon group having an unsaturated bond, X is a halogen or mixture of same, M is Group IVa metal, Eu, Cd, Cu, Fe, Mn or Pd). R is represented by CH3(CH2)nC≡C—C≡CCH2 (n=2-14). It is preferred that M is Pb, and X is a bromine atom.
