WebIn this article, the coarse-grained molecular dynamics simulation combined with the stochastic polymerization model was applied to study the preparation of polymer chain-grafted carbon nanotube (CNT) via the “grafting-from” strategy. The simulation results show that it is feasible to promote the grafting density of the polymer … WebThe molecule, which takes part in the chain transfer reaction, is called (chain) transfer agent. Solvent SH may react with the growing radical as follows: The initiator may also function as a transfer agent: The monomer is also considered a transfer agent (b carbon atom of the radical chain may be transferred to the unsaturated monomer.)

WebAn initiation reaction must occur to functionalize a monomer unit before the reaction can begin. Once a monomer has been functionalized, another monomer unit can bind to it, and the functionalized carbon center propagates to the new monomer unit. In this fashion, monomer units continue to attach to the polymer chain until termination occurs. WebPolymerase chain reaction (PCR) is a technology for exponential amplification of a fragment of DNA.
