    • 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.
    • 公开了具有增强的扩增和内部功能的树枝状聚合物。 这些树枝状聚合物通过使用快速,反应性开环化学(或其他快速反应)结合使用分支细胞试剂以受控方式快速和精确地构建树突状结构,一代代,具有更清洁的化学,通常 单一产品,较低的试剂过量,较低的稀释水平,更高的容量方法,更容易缩放到商业尺寸,新的材料范围以及更低的成本。 制备的树枝状组合物具有新颖的内部功能,更高的稳定性(例如,热稳定性和较少的或没有反向的迈克尔反应),并且在较低的代次下达到包封表面密度。 出乎意料的是,多官能分支细胞试剂与多官能核心的这些反应不产生交联材料。 这种树枝状聚合物可用作油/水乳液的破乳剂,纸张制造中的湿强剂,质子清除剂,聚合物,纳米尺寸单体,用于电子显微镜的校准标准品,制备尺寸选择性膜,以及用于在水性制剂中改性粘度的试剂 作为油漆。 当这些树枝状聚合物具有与其表面和/或内部相关的载体材料时,由于树枝状聚合物的独特特征,例如用于药物递送,转染和诊断,这些树枝状聚合物具有携带材料的附加性质。

    • 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.

    • 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 may be 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.
