Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to an ethylene-propylene rubber catalyst composition. Background technique [0002] Ethylene-propylene rubber is a synthetic rubber with ethylene and propylene as the main monomers. According to the composition of monomers in the molecular chain, it can be divided into binary ethylene-propylene rubber and ternary ethylene-propylene rubber. The former is a copolymer of ethylene and propylene. Expressed in EPM, the latter is a copolymer of ethylene, propylene and a small amount of non-conjugated diene third monomer, expressed in EPDM, both collectively referred to as ethylene-propylene rubber, widely used in automotive parts, waterproof materials for construction, wires Cable sheaths, heat-resistant rubber hoses, adhesive tapes, automotive seals, lubricating oil additives and other products. The existing catalysts for cracking ethylene-propylene rubber have complex manuf...
