Multifunctional agents, characteristics

With the multifunctional linking strategy either homo- or heterofunctional linking agents can be employed. The homo-approach was widely used in the past for the synthesis of well-defined //-stars with predetermined number and molecular characteristics of arms [163]. New applications of these approaches have been recently reported for the synthesis of A2B, A3B and A2B2 type //-stars. 

The selection of an aqueous cleaning system is simplified if only water alone, or water and a commodity chemical alone, are used. The cleaning performance can be somewhat predicted based on solubility characteristics (at the appropriate pH) or by consideration of the peptizing performance of alkalinity on protein or the oxidizing action of sodium hypochlorite on denatured protein. In the case of formulated multifunctional cleaning agents, the performance is more... 

While not related exclusively to block copolymer synthesis, the formation of many of the more complex architectures available through RAFT polymerization - including those based on a single monomer - shares the characteristics and caveats of linear block copolymer formation. One technique to obtain such structures (aldn to the triblock synthesis mentioned above) is the use of higher-level, multifunctional RAFT agents. A synthetic approach with a multifunctional core or a RAFT agent-functionalized polymer backbone allows...
