摘　　要：将负载型茂金属催化剂用于现有的线型低密度聚乙烯(LLDPE)装置上,生产茂金属线型低密度聚乙烯(mLLDPE)。工业生产结果表明,相对于原有的Ziegler-Natta催化剂,使用茂金属催化剂生产mLLDPE的物料消耗、H_2用量、冷剂的浓度都有所降低;mLLDPE薄膜制品的雾度由14.0%降到8.1%,落镖冲击强度由10.8g提高到38.8g。The production of linear low density polyethylene （LLDPE）with the supported metallocene catalyst （mLLDPE） was carried out in an existing LLDPE plant after its revampment. The industrial production shows that using the metallocene catalyst can result in a certain reduction in the consumption of raw materials and hydrogen gas and the concentration of coolant, compared with using the previous Ziegler-Natta catalyst. The haze of the film made of the mLLDPE resin was lowered to 8.1% from 14.0%; the dart impact strength of the film rises from 10.8 g to 38.8 g.
