Dendritic polymers of the macromolecular structure of Figur 1 are disclosed. The dendritic polymers have enhanced amplification and interior functionality. The dendritic polymers are made by use of fact, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled manner to rapidly and precisely build dendritic structures with cleaner chemistry and often with single products. Additional benefits include lower excesses of regents, lower levels of dilution, higher capacity, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The compositions prepared have novel internal functionality, including increased thermal stability and no reverse Michael's reaction, and reach encapsulation surface densities at lower generations.
图 1 公开了大分子结构的树枝状聚合物。树枝状聚合物具有更强的放大和内部功能。树枝状聚合物是通过使用事实、反应性开环化学(或其他快速反应),结合使用分支细胞试剂,以受控的方式快速、精确地构建树枝状结构,化学反应更纯净,通常只有单一产物。其他优点还包括:调节剂用量更少、稀释程度更低、容量更大、更容易扩展到商业规模、材料范围更广、成本更低。所制备的组合物具有新颖的内部功能性,包括热稳定性更高,不会发生迈克尔反向反应,并能在较低世代达到封装表面密度。
