Abstract: Starburst conjugates which are composed of at least one dendrimer in association with at least one unit of a carried agricultural, pharmaceutical, or other material have been prepared. These conjugates have particularly advantageous properties due to the unique characteristics of the dendrimer.

Abstract: In the present invention, an inorganic reactant is, or reactants are, localized with respect to a dendritic polymer by physical constraint within or by a non-covalent conjugation to the dendritic polymer. The localized inorganic reactant or reactants is/are subsequently transformed to form a reaction product which is immobilized with respect to the dendritic polymer. This immobilization occurs on a nanoscopic scale as a consequence of the combined effects of structural, chemical and physical changes without having covalent bonds between the product(s) and the dendritic container and results in new compositions of matter called dendritic nanocomposites. The resulting nanocomposite material can be used to produce revolutionary products such as water soluble elemental metals, with specific applications including magnetic resonance imaging, catalytic, magnetic, optical, photolytic and electroactive applications.

Abstract: A molded plastic beverage cup comprising a generally cylindrical body portion, a rim and a handle, and a method of forming the cup. The body portion has an open upper end, and the rim extends radially outwardly from the perimeter of the open end of the body portion. The handle is formed as an integral part of the cup. The handle extends outwardly from substantially diametrically opposed portions of the rim and then along the rim on one side of the cup between the diametrically opposed portions. The end portions of the handle extend from the rim, and are sufficiently flexible to allow the handle to be bent upwardly from the rim so that the handle arches diametrically across the upper end of the cup. The entire cup is thermoformed from a single sheet of plastic.

Abstract: An electrically conductive polymer is comprised of the reaction product of a dendrimer and an electrophoric compound which exhibits .pi.-stacking upon reduction. The reaction product which is a peripherally modified dendrimer is formed and reduced, either chemically or electrochemically, in a polar solvent. The reduced electrophoric moieties aggregate (form .pi.-stacks) to form electrically conductive pathways. The reduced peripherally modified dendrimers of the invention can be cast into films and other solid forms to provide flexible electrical conductors and semiconductors. The conductive polymers of the invention exhibit electrical conductivities comparable to that of doped polyacetalene, but are oxygen and moisture stable.

Abstract: 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.

Abstract: A water-soluble or water-dispersible fluorine-containing dendritic polymer surfactant having at least one terminal fluorocarbon moiety and at least one terminal anionic moiety, and which is suitable for use in preparing protective coating compositions is disclosed. The water-soluble or water-dispersible fluorine-containing dendritic polymer surfactants are represented by the general formula: ##STR1## where D represents a dendritic polymer, R.sub.F represents a fluorocarbon containing moiety, A.sup.- represents an anionic containing moiety, C.sup.+ represents a cation, T represents a terminal group of the dendritic polymer which has not been functionalized with a fluorocarbon or anionic moiety, n and m are at least each at least one, and the sum of n+m+q is the total number of terminal groups on the dendritic polymer. Also disclosed is a coating composition capable of forming a highly crosslinked, non-stick, protective coating.

Abstract: Dendritic polymer conjugates which are composed of at least one dendrimer in association with at least one unit of a carried material, where the carrier material can be a biological response modifier, have been prepared. The conjugate can also have a target director present, and when it is present then the carried material may be a bioactive agent. Preferred dendritic polymers are dense star polymers, which have been complexed with biological response modifiers. These conjugates and complexes have particularly advantageous properties due to their unique characteristics.

Abstract: 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.

Abstract: 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.

Abstract: Dense star polymers or dendrimers having a highly branched interior structure capable of associating or chelating with metal ions are modified by capping with a hydrophobic group capable of providing a hydrophobic outer shell.

Also dense star polymers or dendrimers having a highly branched hydrophilic interior structure are modified by capping with a hydrophobic group capable of providing a hydrophobic outer shell, which modified polymers are useful as gels and surfactants.
