| titleOfInvention | Method for producing propylene-ethylene block copolymer |
| abstract | (57) Abstract: A method for producing a propylene-ethylene block copolymer having high stereoregularity and a wide molecular weight distribution, and having excellent rigidity and impact resistance, while easily controlling the molecular weight with hydrogen. To provide. SOLUTION: Component [A]: solid titanium compound [B] component: organoaluminum compound R 3 Al [I] represented by the general formula [I] (where R is an alkyl group having 1 to 10 carbon atoms). Component [C]: an organosilicon compound represented by the general formula [II] (However, n is an integer of 2 to 6, R 1 and R 2 are hydrogen or a methyl group, and R 3 and R 4 are the same or different and have 1 to 1 carbon atoms. An alkyl group having 4 carbon atoms, a cyclic alkyl group having 3 to 6 carbon atoms, or an aryl group; R 5 is an alkyl group having 1 to 3 carbon atoms; In the first step of the polymerization, the polymerization of propylene alone or an α-olefin other than propylene is carried out in the presence of the catalyst for olefin polymerization represented by A method for producing a propylene-ethylene block copolymer, wherein the polymerization of propylene and ethylene is performed in the second step so as to be 10 to 50% by weight of the total amount of polymerization. |
