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.

摘要： This invention provides a cost effective process and new Janus dendrimers where at least two dendrons are attached at the core (with or without a connector group) and where at least two of the dendrons have different functionality. Preferred are those Janus dendrimers where at least one dendron is a PEHAM dendron. Thus these Janus dendrimers are heterobifunctional in character and use unique ligation chemistry with single site functional dendrons, di-dendrons and multi-dendrons. Also included are Janus dendrons which maybe used as intermediates to make the Janus dendrimers or to further react with another reactive moiety. These Janus dendrimers can provide several new dendrimer moieties, namely: combinatorial libraries of bifunctional structures; combined target director and signaling dendrimers; specific targeting entities for diagnostic and therapeutic applications, such as for example targeted MRI agents, targeted radionuclide delivery for diseases such as cancer, and targeted photosensitive or radiowave sensitive agents.

摘要： The present invention describes a process for preparing new looped dendrimer and dendron compounds by controlling the molar amount of branch cell reagent monomer that is combined with various cores bearing core-XR functionalities (e.g., primary, or secondary amines, thiol, or epoxy functionalities). These looped, macrocyclic structures are more robust to various conditions, with greater resistance to acid/base hydrolysis. Alternatively, the looped, macrocyclic structure may offer new orientations that would qualify it as a better chelation ligand for metals, and other similar uses.

摘要： 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.

摘要： A novel process for preparing poly(2-isopropenyl-2-oxazoline or oxazine) and its methyl methacrylate copolymer, which are useful as water borne curing agents, particularly in the non-stick coating industry. The process converts commercially available poly(methyl methacrylate) into poly(2-isopropenyl-2-oxazoline or oxazine) polymers or copolymers with methyl methacrylate, while circumventing the use of the highly toxic monomer, 2-isopropenyl-2-oxazoline or oxazine. The process involves converting a poly(methacrylic ester) to the corresponding poly(.beta.-hydroxy-N-ethyl or propyl methacrylamide) and activating the ring-forming .beta.-hydroxy-N-ethyl or propyl methacrylamide moiety to form an oxazoline or oxazine ring.

摘要： Dendritic polymers containing disulfide functional groups which are essentially inert under non-reducing conditions, but which form sulfhydryl groups upon being subjected to a reducing agent are prepared by synthesizing dendritic polymers having a core with a disulfide linkage or by reacting a dendritic polymer with a molecule containing a disulfide linkage and reactive terminal groups. In one aspect of the invention, dendritic polymers having a single disulfide functional group at the core are provided. The single disulfide group at the core can be reduced to form two sulfhydryl groups to which other molecules, such as proteins, oligonucleotides, peptides, hormones, other dendritic polymers, non-dendritic polymers, etc., can be bound. Applications for the disulfide functionalized dendritic polymers include formation of differentiated dendrimers, formation of binding reagents for diagnostics, drug delivery, gene therapy and magnetic resins imaging, and in the preparation of self-assembled dendrimer monolayers on a quartz crystal resonators to provide dendrimer-modified electrodes which are useful for detecting various ions or molecules. In another aspect of the invention, dendritic polymers having sulfhydryl terminals are provided. The sulfhydryl terminated dendritic polymers can be used to prepare stable, curable resins composition which can undergo cross linking when subjected to a reducing agent.

摘要： The specification discloses a process for producing poly-branched polymer having relatively high molecular weight by forming a first set of branches by polymerizing monomers which are either protected against or are non-reactive to branching and grafting during polymerization, grafting that first set of branches to a core having a plurality of reactive sites capable of reacting with the reactive end units of said branches, either deprotecting or activating a plurality of monomeric units on each of said branches to create branch reactive sites, forming a second set of branches in the same manner as the first set of branches were formed, grafting the second set of branches to the first set of branches by reacting the reactive end units of the second set of branches with each said branch reactive site on said first set of branches and repeating the foregoing steps reiteratively to form and attach subsequent sets of branches to prior branch sets until a desired number of iterations has been effected.
