Title:
PREPARATION METHOD FOR CATALYST FOR ETHYLENE POLYMERIZATION AND COPOLYMERIZATION, CAPABLE OF CONTROLLING PARTICLE SIZE
Document Type and Number:
WIPO Patent Application WO/2014/189187
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a catalyst for ethylene polymerization and copolymerization, capable of providing a polymer having a high apparent density and a uniform particle size, and furthermore capable of easily controlling the particle size of the polymer. More specifically, the present invention comprises the steps of: (1) preparing a magnesium compound solution by reacting a magnesium halide compound with one or more kinds of alcohols and one or more kinds of cyclic ethers; (2) preparing a precursor by adding a titanium compound to the magnesium compound solution prepared in (1); and (3) preparing the catalyst by reacting the precursor with the titanium compound. In particular, by controlling the amount of the alcohols and the cyclic ethers used in step (1), the particle size of the polymer can be easily controlled, and furthermore, the catalyst for highly active ethylene polymerization and copolymerization, capable of providing the polymer having a high apparent density and a uniform particle size, can be easily prepared.
