Kinetics and Modeling of Semi-Batch RAFT Copolymerization with Hyperbranching

This work reports a kinetic model developed to provide insight into branching mechanisms and control of gelation by semibatch controlled radical copolymerization processes. The semibatch RAFT copolymerization of acrylamide (AM) and N,N′-methylenebis­(acrylamide) (BisAM) in the presence of 3-benzyltrithiocarbonyl propionic acid (BCPA) as chain transfer agent (CTA) was carried out for the model validation. The BisAM was fed to the reactor at a …
