  Poly(ester-acrylate) and poly(ester/epoxide) dendrimers. These materials can be synthesized by utilizing the so-called “sterically induced stoichiometric” principles. The preparation of the dendrimers is carried out by reacting precursor amino/polyamino-functional core materials with various branch cell reagents. The branch cell reagents are dimensionally large, relative to the amino/polyamino-initiator core and when reacted, produce generation=1 dendrimers directly in one step. There is also a method by which the dendrimers can be stabilized and that method is the reaction of the dendrimers with surface reactive molecules to pacify the reactive groups on the dendrimers.

  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.
