Dendritic polymers of the macromolecular structure of Figure 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. |
