In my experiment, I need to add three monomers to the solvent. Adjust the content of different monomers to obtain the materials I need. Now, I have a rough idea of what the polymer content is for me. Can I keep the molar mass of all monomers unchanged and control he molar mass fraction of two or three monomers to change? They all contain double bonds.
Dear Zhong Zheng, if these are conventional addition polymerization monomers, their relative reactivities are known, i.e., their reactivity ratios will help to estimate the relative presence and most probable sequence distribution of the three monomers along the chains, but it stays only a rough approximation. NMR is the best tool to analyse the the synthesized tripolymer. My Regards
Dear Zhong Zheng, as far as I know about RAFT polymerization technique first synthesize single block copolymer, then Di and at lastly Triblock Copolymer, and also added it simultaneously which will react and grow the chains according to their relative reactivities and then compare the NMR of both the polymers. Choose the best one.
