| titleOfInvention | Application of rare earth compound with constrained geometry configuration in high-selectivity conjugated diolefin-styrene random or block copolymerization |
| abstract | The invention discloses application of a rare earth compound with constrained geometry configuration in high-selectivity conjugated diolefin-styrene random or block copolymerization. The conjugated diolefin-styrene random copolymerization is catalyzed by using a catalysis system consisting of the rare earth compound with constrained geometry configuration, the conversion rate of the monomer is 94percent, the polymerization activity is 2.5*106g molLn-1h-1, the number-average molecular weight of the random copolymer is 0.01 to 1 million, the molecular weight distribution is 1.20 to 2.00, the styrene content of the random copolymer is 4 to 85 mol percent, and the cis-1,4 content of a conjugated polydiene segment is 90 percent. The conjugated diolefin-styrene block copolymerization is catalyzed by using the catalysis system, the conversion rate of the monomer is 100 percent, the polymerization activity is 1.5*108g molLn-1h-1, the number-average molecular weight of the block copolymer is 0.05 to 1.5 million, the molecular weight distribution is 1.20 to 1.50, the styrene content of the block copolymer is 5 to 91 mol percent, the syndiotacticity of a polystyrene segment is 100 percent, and the cis-1,4 content of the conjugated polydiene segment is 97 percent. |
