| abstract | A 6-methoxypyridineimide iron complex and its preparation method and its application in the preparation of high cis polyconjugated diene. The invention belongs to the field of conjugated diene catalytic polymerization. The present invention solves the technical problem that the existing iron-based catalyst has low reaction activity for catalyzing cis-isoprene polymerization. The present invention uses 6-methoxypyridineimide iron complex as the main catalyst to catalyze the polymerization of conjugated diene monomers, and the obtained polyconjugated diene has high molecular weight and narrow molecular weight distribution, specifically: the obtained polyconjugated diene The number-average molecular weight of diene is 130,000 to 300,000, and the molecular weight distribution is 1.4 to 2.0; the microstructure of the polymer is cis-1,4 structure accounting for 80%-95%, trans-1,4 structure accounting for 80%-95% The proportion is 0%-10%, and the content of 3,4-structure and 1,2-structure is 0%-20%. |
