| titleOfInvention | A kind of method for preparing polyolefin by light-induced organic catalysis |
| abstract | The invention discloses a method for preparing polyolefin by light-induced organic catalysis. An olefin monomer, an alkyl halogen initiator and a 5,10-diaryl-5,10-dihydrophenazine organic photocatalyst react under illumination . The invention utilizes the characteristics of visible light catalysts such as low absorption of photon energy, good solubility, stable catalyst structure, wide absorption wavelength, strong excited state reduction potential, fast catalytic polymerization reaction speed and the like, and can efficiently catalyze alkyl halogen initiators to initiate polymerization of olefin monomers, not only The problem of metal residues in the polymer is effectively avoided, and the efficient preparation of polyolefin polymers without metal residues is realized, and the polymerization reaction speed is fast, the molecular weight of the polymer is controllable and the molecular weight distribution is narrow, and the obtained polymer is used as an electrical material or biological material. It has great advantages and solves the defects of the prior art such as high light source energy, unstable catalyst structure, low catalyst catalytic activity, low polymerization initiation efficiency, and metal residues. |
