| titleOfInvention | Method for continuous vapor phase polymerization of propylene |
| abstract | (57) [Summary] [Structure] A solid catalyst component containing Mg, Ti, a halogen and an electron donating compound as the component (A), and the component (B). As propylene in the presence of at least one selected from the group consisting of organometallic compounds of Group IA, IIA, IIB, IIIB and IVB metals of the periodic table and a catalyst comprising an electron donating compound as component (C) When carrying out continuous gas phase polymerization, the catalyst and liquid propylene are brought into contact with each other at a temperature of 50 ° C. or less and an average residence time of 1 minute or more and 60 minutes or less under a full liquid condition, and 0.005% or more of liquid propylene to be supplied 5 % To 1 g of the solid catalyst component (A) per 1 g of the solid catalyst component (A) to form a prepolymerization catalyst, and then the prepolymerization catalyst is added to the gas phase polymerization reactor using unreacted liquid propylene as a carrier medium. Supply continuously, A continuous vapor phase polymerization method of propylene, which comprises polymerizing 10000 g or more per 1 g of the solid catalyst component (A). [Effect] A polymer having a good particle shape and a good product quality can be stably obtained in a high yield and economically. |
