    摘要： The present invention concerns poly(etherhydroxylamine) PEHAM dendritic polymers wherein they function as excipients for the enhancement of water solubility of poorly water soluble (hydrophobic) Active Materials or enhancement of oil solubility of poorly oil soluble (hydrophilic) Active Materials. These dendritic polymers can have Active Materials associated with them by one or more of the following: (a) by adsorption onto the surface or (b) encapsulation into the interior of the dendritic polymers or (c) a mixture of both where these interactions are driven by one or more of the following (i) electrostatic attraction, (ii) hydrogen bonding between dendritic polymers and Active Material and (iii) hydrophobic or hydrophilic interactions or mixtures of these interactions. Additionally, these associated Active Materials can be associated with dendritic polymers through chemical bonding to the surface or to internal functionalities (IF) of PEHAM dendritic polymers or both. Such bonding is done either directly between PEHAM dendritic polymers and Active Material molecules or via a linker that can have a hydrolysable bond to the Active Material. In addition, a chemical entity with strong interaction to the Active Material and dendritic polymers can be associated with the dendritic polymer prior to adsorption or encapsulation of the Active Material or together with the Active Material.

    摘要： Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.
