| titleOfInvention | Ternary polymerization catalyst of norbornene, octafluorocyclopentene and styrene and ternary polymerization method |
| abstract | The invention relates to a ternary polymerization catalyst of norbornene, octafluorocyclopentene and styrene and a ternary polymerization method, wherein the catalyst is prepared through a following method comprising steps of: 1) dissolving neodymium trichloride, diethyl zinc and a ligand compound in a first solvent in a dried single-mouth glass bottle under an inert gas atmosphere; 2) sealing the mouth of the bottle by a latex pipe, performing a reaction at a constant temperature of 40-60 DEG C for 20-30 min to prepare a neodymium/zinc complex catalyst; 3) according to a ratio of 1:1:1, adding a norbornene monomer, an octafluorocyclopentene monomer and a styrene monomer into a high-pressure kettle which is vacuumized for several times and is filled with nitrogen, and adding a second solvent to dissolve the raw materials; 4) adding the neodymium/zinc complex catalyst, and carrying out a reaction at 20-90 DEG C for 0.1-6 MPa for 1-6 h; and 5) washing a reaction product to obtain a terpolymer. The raw materials of the catalyst are low in cost and are easy to obtain. The catalyst can generate catalytic activity at a low temperature and is high in catalytic efficiency. A product is very easy to wash and separate and the method is high in yield of the co-polymer. |
