| titleOfInvention | Method and catalyst for preparing high cis-polybutadiene by gas-phase polymerization |
| abstract | The invention discloses a method and catalyst for preparing high cis-polybutadiene by gas-phase polymerization. The catalyst is mixed by five components, wherein the first component is a rare-earth compound; the second component is alkyl aluminum, alkyl aluminium hydride or alkylaluminoxane; the third component is alkyl chloride or alkyl aluminum chloride; the fourth component is magnesium chloride, silicon dioxide, carbon black or aluminum oxide; the fifth component is any one or combination of more of nano silicon dioxide, nano carbon black, nano aluminum oxide, nano titanium dioxide, nano antimony trioxide, nano calcium carbonate, nano talcum powder and nano montmorillonite; and the mol ratio of the first component to the second component is 1:(20-100), the mol ratio of the first component to the third component is 1:(1-10), the ratio of the molar weight of the first component to the mass of the fourth component is 1:(2000-200000), and the mass ratio of the fifth component to the fourth is 1:(0.125-200). Butadiene and a catalyst are subjected to gas-phase polymerization reaction at 40-70 DEG C for more than 30 minutes to obtain the high cis-1,4-polybutadiene rubber particles. |
