| titleOfInvention | Production of propylene block copolymer |
| abstract | PURPOSE: To obtain a block copolymer having a small amount of formed low crystalline part, slightly causing aggregation and anchorage, having improved low-temperature impact resistance, by carrying out block copolymerization by specific two processes in the presence of a catalyst obtained by combining three components. n CONSTITUTION: A propylene-ethylene block copolymer is obtained by polymerization of the following two processes in the presence of catalyst obtained by combining three components of (A) a solid composition comprising magnesium, titanium and a halogen as essential components, (B) an organoaluminum compound and, (C) an amine compound having steric hindrance. (i) Propylene alone or a mixture of propylene/ethylene is polymerized at one stage or multiple stages to form 60W95wt% based on the final amount of polymer of a propylene polymer or a propylene-ethylene copolymer containing ≤7wt% ethylene. (ii) A mixture of propylene/ethylene is polymerized at one stage or multiple stages to form a propylene-ethylene copolymer containing 20W100wt% ethylene. n COPYRIGHT: (C)1986,JPO&Japio |
