Polymerization characteristics of DMPT N,N-Dimethyl-p-toluidine CAS 99-97-8
N,N-dimethyl-p-toluidine can not initiate the polymerization of acrylonitrile (AN) in the dark, but it initiates the polymerization very quickly when exposed to light. Figure 1 shows the photopolymerization of acrylonitrile (AN) in the presence of N,N-dimethyl-p-toluidine, naphthalene, benzophenone (BP)-triethylamine (TEA) and the polymerization in the presence of ABlN. The speeds are respectively 0.157, 0.023, 0.139 and 0.045% points-1, indicating that N,N-dimethyl-p-toluidine is an extremely effective initiator for photopolymerization of acrylonitrile (AN). N,N-dimethyl-p-toluidine initiates acrylonitrile (AN) Photopolymerization is carried out by free radical mechanism. When the micro-Chemicalbook amount of free radical scavenger was added, the polymerization completely stopped. For example, [N,N-dimethyl-p-toluidine]-10-3M, when 200ppm 2,2,6,6-tetramethylpiperidinol nitroxide radicals are added, acrylonitrile (AN) will not be illuminated for 1.5 hours. Any polymerization, without adding a free radical scavenger under the same conditions, a white polyacrylonitrile precipitate appears within two minutes.
Application of DMPT N,N-Dimethyl-p-toluidine CAS 99-97-8
Used as an effective photoinitiator for the polymerization of acrylonitrile (AN), the polymerization speed is proportional to the 1.62 power of the AN concentration and the 0.62 power of the DMT concentration. The product is usually used as an accelerator, and can also be used as an additive for the synthesis of unsaturated polyesters and adhesives.
