| titleOfInvention | Method for preparing catalyst for polymerization of butadiene and copolymerization of butadiene with coupled dienes |
| abstract | FIELD: chemistry of polymers, chemical technology, catalysts. n SUBSTANCE: invention relates to a method for preparing a catalyst used in polymerization of butadiene and copolymerization of butadiene with coupled dines. Method involves interaction of components comprising the compound of rare-earth element, diisobutyl aluminum hydride, triisobutyl aluminum, alkyl aluminum halide and coupled diene. Firstly, method involves mixing rare-earth element and coupled diene solutions with diisobutyl aluminum hydride solution, and the mixture is kept for 10-30 min at stirring, and then triisobutyl aluminum and alkyl aluminum halide solutions are added. After mixing all components the mixture is kept for 10-15 h in the following mole ratio of components: rare-earth element : diisobutyl aluminum hydride : triisobutyl aluminum : alkyl aluminum halide : coupled diene = 1:(3-12):(6-12):(1.5-3):(2-20), respectively, wherein rare-earth element carboxylate or alcoholate is used as a source of rare-earth element. Invention provides preparing the high-effective catalyst allowing preparing highly stereoregular polybutadiene and butadiene copolymer with the couples diene with simultaneous reducing the range of molecular-mass disposition by 3-3.5 times. n EFFECT: improved preparing method. n 5 ex |
