POLYMERIZATION CATALYST COMPOSITION, METHOD FOR PRODUCING SYNTHETIC POLYISOPRENE, AND SYNTHETIC POLYISOPRENE |
摘要 |
A polymerization catalyst composition that, without accompanying excessive gelation, allows efficient synthesis of high molecular weight polyisoprene under industrial conditions is provided. The polymerization catalyst composition contains:
a rare earth element compound (component (A)) represented by the following general formula (i):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒM-(NQ 1 ) (NQ 2 ) (NQ 3 )€ƒ€ƒ€ƒ€ƒ€ƒ(i);
at least one (component (B)) selected from an ionic compound and a halogen compound; and
a compound (component (C)) represented by the following general formula (X):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒYR 1 a R 2 b R 3 c €ƒ€ƒ€ƒ€ƒ€ƒ(X). |
