| In principle, the compounds should be added as following order: monomer, solvent (dissolving and degasing), initiator (degasing), catalyst (degasing), and then finally the ligand (degasing at least three times). Without ligand the reaction will not start, therefore, you are safe to add it at the latest step. I'm sure you are going to succeed if you follow this. The particles you observed during the polymerization is a bad sign, which normally suggests the polymerization fail. Good luck! |
