  • Publication number: 20080255320
    Abstract: Polyamidoamine (PAE) resins are prepared from polyamidoamine made with excess amine, which are reacted with a specifically defined amount of difunctional crosslinker. The amount of difunctional crosslinker used is based on the polyamidoamine amine number and reduced specific viscosity (RSV). The PAE resin is prepared by first synthesizing a polyamidoamine from a polyamine and a polycarboxylic acid or polycarboxylic acid derivative, wherein the polyamine is present in a molar excess, said molar excess being from about 1.02 to 2.00, then reacting the polyamidoamine with difunctional crosslinker, wherein the weight % of difunctional crosslinker to polyamidoamine solids is no more than about 0.308(amine number/RSV)—9.18 or 385(amine number/RSV)—5.20, wherein the amine number is expressed as the milliequivalents of amine per gram of polyamidoamine solids and the RSV is the reduced specific viscosity measured at 2% concentration in 1 M NH4Cl expressed in deciliters per gram.

  • Publication number: 20080248126
    Abstract: Methods for efficient preparation of drug-polymer (or oligomer) conjugates which are useful in the preparation of particles, including microparticles and nanoparticles, for delivery of the drug in vivo for therapeutic applications. The invention additionally provides certain drug-polymer and drug-oligomer conjugates which are useful in the preparation of particles for delivery of the drug in vivo. The invention also provides nanoparticles of this invention prepared by nanoprecipitation using drug-polymer/oligomer conjugates of the invention. The drug conjugates are formed during polymerization of the polymer or oligomer in which the drug is employed as an initiator of the polymerization of the monomers which form the polymer and/or oligomer. More specifically, the drug conjugates are formed by ring-opening polymerization of cyclic monomers in the presence of an appropriate ring-opening polymerization catalyst and the initiator (the drug).

  • Publication number: 20080221299
    Abstract: Disclosed are wholly aromatic polyamide filament and a method of manufacturing the same, characterized in that, in a process of preparing wholly aromatic polyamide polymer, a multiple tubular feed pipe for polymeric monomer and polymerization solvent with specific construction of adjacent inner paths 11a and outer paths 11b which are alternately arranged one another is used to feed either aromatic diacid chloride A or aromatic diamine dissolved in the polymerization solvent B into a polymerization reactor 20 through corresponding one among the inner and outer paths 11a and 11b. The present invention is effective to progress uniform and homogeneous polymerization over all of area of a polymerization reactor 20 leading to reduction of deviation in degree of polymerization, since polymeric monomers are miscible and react together very well immediately after putting the monomers into the reactor 20.
