    • Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymer are made by use of fast, reactive ring opening chemistry (or other fast reactions) combined with the use of branch cell reagants in a controlled way to rapidly and precisely build dendrimer structures, generation by generation, with precise structures with cleaner chemistry, typically single products, lower excesses of reagants, lower levels of dilution, higher capacity method, more easily scale to commercial dimensions, new ranges of materials, and lower cost. The dendrimer composition prepared have novel internal functionality, greater stability, e.g., thermal stability and less or no reverse Michaels reaction, and which reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of poly-functional branch cell reagents with polyfunctional surfaces do not create gelled materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, 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 have additional properties due to the unique characteristics of the dendritic polymer.
    • 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)结合使用分支细胞反应物以受控的方式制备,以快速和精确地构建树枝状聚合物结构,一代代,具有更清洁化学物质的精确结构 ,通常是单一产品,较低的反应物过剩,较低的稀释水平,更高的容量方法,更容易扩展到商业尺寸,新的材料范围和较低的成本。 所制备的树枝状聚合物组合物具有新的内部官能团,更高的稳定性,例如热稳定性和更少或没有反向迈克尔斯反应,并且在较低代次下达到包封表面密度。 出乎意料的是,具有多官能表面的多功能分支细胞试剂的这些反应不产生胶凝材料。 这种树枝状聚合物可用作油/水乳液的破乳剂,制造纸中的湿强剂,质子清除剂,电子显微镜校准标准品,制备尺寸选择性膜,以及用于改进水性配方如油漆中的粘度的试剂。 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,这些树枝状结构具有额外的性质。
