Abstract
The invention relates to a preparation method of an organic vehicle olefin polymerization catalyst. The preparation method of the organic vehicle olefin polymerization catalyst comprises the following steps: mixing alcohol with water, thus obtaining a dispersion liquid; adding a reactive monomer into the dispersion liquid, thus obtaining mixed solution; adding a stabilizer, metal oxide particles and a free radical initiator into the mixed solution, heating to 60-85 DEG C, stirring while reacting for 3-12 hours to obtain a reaction product, washing the obtained reaction product, and drying, thus obtaining a copolymer containing metallic oxide, wherein metal in the metal oxide is one or combination of more than one of metal ions in families VIII, IB, IIB and IIA; and removing metallic oxide in the copolymer containing metallic oxide, washing and drying, thus obtaining the organic vehicle olefin polymerization catalyst. The preparation method of the organic vehicle olefin polymerization catalyst has the advantages that the form and the specific surface area of an organic vehicle can be regulated, and thus the organic vehicle can be separated out from a system relatively easily, solid particles can be filtered out relatively easily, the yield of a reaction monomer is increased, and the organic vehicle with the narrow particle size distribution is obtained.
