摘要： A modified supported catalyst composition for polymerizing olefins, particularly alpha-olefins, for example, ethylene or ethylene and 1-hexane, is prepared by combining a chromium compound-containing catalyst with a modifier which is an oxide of an element of Group IIIA of the Periodic Table of the Elements. The modifier contains a small quantity of water. The resulting modified catalyst composition produces polymer resins having higher values of High Load Melt Index -HLMI (I.sub.21) than catalyst compositions without the modifier.There is also disclosed a process for polymerizing olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the above-identified modified catalyst composition. The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.

摘要： A unique high efficiency catalyst for the polymerization of alpha-olefins has been developed based on the use of methanol treated magnesium oxide as support, an equimolar mixture of titanium tetrachloride and tetrabutyltitanate as titanium source impregnated on the support, and an organoaluminum compound as reducing agent. The polyethylene produced by this catalyst has narrow molecular weight distribution, high bulk density, high melt index, and minimum catalyst residue due to the high polymer to catalyst ratio. The copolymers produced by this catalyst have narrow molecular weight distribution, but have lower bulk density, low melt index and low density.

摘要： A supported catalyst for polymerizing 1-olefins, for example, ethylene, is prepared by depositing a chromium compound and a titanium compound on a refractory oxide support which is substantially non-spherical, and which has a relatively broad particle size distribution range. The catalyst is preferably combined, either outside of the polymerization vessel or in situ, with a sufficient amount of at least one magnesium composition of the formula RMgR', where R and R' are the same or different and they are C.sub.1 to C.sub.12 hydrocarbyl groups, to provide a molar ratio of magnesium to chromium in the catalyst composition of about 0.01:1 to about 25:1. The resulting catalyst composition has good feedability and fluidization characteristics, and it produces resins of relatively high HLMI at relatively low temperatures.There is also disclosed a process for polymerizing 1-olefins, at relatively lower temperatures than was heretofore possible, to obtain resins of relatively high HLMI, using the above-identified catalyst composition. The resulting polymers can be used for the fabrication of blow-molded products, e.g., household and industrial containers.
