A method of production of ethylene-based polymer particles includes the steps of: homopolymerizing ethylene or copolymerizing ethylene and a linear or branched α-olefin having 3 to 20 carbon atoms in the presence of an olefin polymerization catalyst including: (A) fine particles having an average particle diameter greater than or equal to 1 nm and less than or equal to 300 nm obtained at least by the following two steps: (Step 1) causing contact between a metal halide and an alcohol in a hydrocarbon solvent; (Step 2) causing contact between a component obtained by (Step 1) and an organoaluminum compound and/or an organoaluminumoxy compound; and
(B) a transition metal compound represented in General Formula (I) or (II), And (E) an intrinsic viscosity [η] of the ethylene-based polymer particles, measured in decalin at 135°C, is from 5 to 50 dL/g.
摘要:
To provide capsular fine particles comprising an olefinic polymer which have a uniform particle size distribution and a uniform particle size, and which are spherical and free from the coagulation between particles. Capsular fine particles comprising the olefinic polymer, of which the ratio (L/M) of the outer diameter (L) to the inner diameter (M) is 1.1 to 6.0, and the average diameter is 0.6 to 40 µm.
