| titleOfInvention | Catalytic system for synthesizing polyacrylamide and synthesis method of polyacrylamide |
| abstract | The invention discloses a catalytic system for synthesizing polyacrylamide and a method for synthesizing polyacrylamide. The catalytic system comprises a catalyst with a molar ratio of 1: (0.5-2.5): (2.5-5): (0.8-1.5): chloroacetic acid, (1.5-2.5) Y (OTf) 3 、AlCl 3 、Cu 2 O and tetramethylethylenediamine. The invention establishes that chloroacetic acid is used as an initiator and matched with a catalyst Cu 2 O and complexing agent tetramethyl ethylenediamine to form an ATRP polymerization system suitable for acrylamide monomer, and two Lewis acids Y (OTf) are introduced 3 And AlCl 3 The polyacrylamide which is used as a directional polymerization control agent and has narrow molecular weight distribution and certain stereoregularity is synthesized by adjusting the use ratio of the directional polymerization control agent. |
