  • Patent number: 11505496
    Abstract: Embodiments of the invention relate to concrete admixtures, provide a phosphonato block polymer, a preparation method and an application. The method includes: the phosphonato block polymer prepared by copolycondensating an ether-type segment A, a phosphonato segment B, and a third part of aldehyde C. The ether-type segment A is obtained by polycondensating a polyether monomer and a first part of aldehyde C. The phosphonato segment B is obtained by polycondensating a monomer b containing phosphonato, a monomer c, and a second part of aldehyde C in an aprotic weak polar solvent E. By preparing a block polymer using arylalkane as a main chain and using a phosphonic acid or phosphinic acid functional group as an adsorption group, the invention improves the resistance of the block polymer to sulfate and clay interference, and can achieve initial high dispersion of concrete with a low water-cement ratio and decreasing of the system viscosity.

  • Patent number: 8440787
    Abstract: The present invention provides hydmoxyapatite-targeting, multiarm polymer reagents suitable for reaction with biologically active agents to form conjugates, the polymeric reagents comprising one or more polymer chains and a plurality of hydroxyapatile-targeting moieties located at the terminus of one or more of the polymer chains. The multiarm polymers are optionally divided or separated by one or more degradable linkages into polymer segments having a molecular weight suitable for renal clearance. The polymeric reagents of the invention can have a substantially linear structure, although branched or multiarm structures are contemplated as well. The invention is suited for applications in which use of a high molecular weight polymer is desired, such as a total polymer number average molecular weight of at least about 30,000 Da for linear polymers and 20,000 Da for multiarm polymers. Each structure includes one or more linkages capable of degradation in vivo.

  • Publication number: 20130092918
    Abstract: The present invention is to provide a method of favorably forming an organic EL device with the inverted structure by the wet process. On that account, an organic EL device includes a cathode, an electron injection layer, a light emitting layer, a hole transport layer, a hole injection layer, an anode are formed in this order on a substrate. The electron injection layer is formed by applying ink between banks and drying the ink. The ink is formed by dissolving a polymer compound having an organic phosphine oxide skeleton in an alcohol solvent. The light emitting layer is formed by applying ink between components of the bank and the drying the ink. The ink is formed by dissolving material for light emitting layer such as polyphenylene vinylene (PPV) derivative or polyfluorene derivative in a nonpolar solvent.

  • Patent number: 8268959
    Abstract: This invention describes the synthesis and use of novel energetic poly(phosphazene) materials suitable for binding high explosives. These materials may also be used as explosives in their own right. The materials possess high energy density and are highly amenable to chemical modification thereby allowing for modification to the physical properties of the material. In particular the tacky and rubbery nature of these materials makes them ideal for use as binder and co-binder materials.
